Mikrotik LDF5 firmware image download Help Needed

Has anyone tried loading the "Microtik First Install Process" using the "Windows Procedure"? Lately?
Under "DOCS, GETTING STARTED GUIDE,  Installing AREDN Firmware", "Mikrotik First Install Process"
Please read below and enlighten me on what I might be doing wrong.  Thanks!!!
1. I have a new Mikrotik LDF 5 that I'm trying to load the AREDN firmware package (step 1) on to.
2. Everything seems fine up to the pont in the AREDN Mikrotik "Windows Procedure" step 5 and 6. 
3. I get to the end of step 5 and it says hold the reset button until you see "TFTPd: DoReadFile: rb.elf"
in the Tiny PXE log window.
4. I do see that line appear in just a couple of seconds in the log window.
5. Instructions say release the reset button, which I did, BUT information keeps scrolling down in the window, showing it loading more files (apparently).
6.  It says a bunch of some stuff about sent...
discovered...
stuff over and over again with different IP addresses scrolling down.
7.  This goes on for over 2 hours now.  Does it take hours to load? No info in the instructions on what to expect here.
8.  On a previous attempt (after step above, I did follow the instructions to click the "offline" button immediately after the "...DoRead..."
but the ping to the IP address 192.168.1.1 or the admin page address fails to connect.  It seems like I'm missing something important around this stage of the procedure. 
thanks for any help!

I got past this trouble spot.
I'm not sure what was wrong.  It seemed to start working correct (the extra scrolling data stopped showing up) after another try.  at step 5 above, I select the pxesrv stop button and then after maybe a minute the ldf5 ligts stop flashing and I am then able to get into the nocall IP setup screen.
Then things go bad again.  I keep getting locked out after I follow the on screen instructions to set the node name/password and reboot.
Again I am locked out. I don't know why.  None of the login names I was given work to get back in to continue configuring.
There is confusing info about the blockownerincription package that I don't understand in the splash screen that comes up when I'm first able to get logged into the ldf5 and will ignore for the time being.

I have tried several times and keep getting locked out when I try to follow the setup instructions after I get in initially.   The instructions about needing to be connected to the internet are confusing.  Does it mean connect to the WWW net or just the local net for the node.  I don't know of a way to connect to the WWW and the local node at the same time.  I think it means just to get on the WWW to download the upgrde package (but those instructions were earlier already), then go back to the local node only.  maybe?

Well after hours of trial and error, I got it to connect.
There seems to be issues when saving changes and rebooting.  It seems that the userID of root, never updates.  I had to keep trying different user IDs and passwords, and then I found the magic combination (trial and error again) to get into it.  Change one or 2 things and reboot each time seems to help figure out what is going on once you get initially connected.

The "Charts" "Sound On" is working now, so that is helping me aim toward Mt Wilson (32 miles distant) with the LDF5 mounted on a Winegard 30" dish.  I was able to pick up a few more dB of SNR with that.  Sig is at -74 on the scan mode.  for about a 20 to 22 dB SNR   LQ 95%, NLQ 47% Txmpbs is only about 1.1 to 2 which is pretty much too slow to be useful I think. Discouraging.

I also have a Ubiquity Nanobeam M5-300a pointed at Mt. Wilson on my roof. The SNR is only 12 dB  LQ and NLQ are 55 and 89 respectively with a Mbps of 6 to 8
It seems quite a bit better bit rate than the Mikrotik even thought it is a much smaller antenna/dish and the poor SNR.
