The UID file is for my local area (Indianapolis area). It's taken me a few to figure this out so I fell your pain. Once you get it you'll slap your head and say Ahhh!!!
Here's what I suggest. Copy the following 8 lines so they're in your clipboard (this is just an example for learning how this all works, your UIDs will be different).
41111 LOGTEXT=DISP JOHNSON COUNTY
41112 LOGTEXT=DISP JOHNSON COUNTY
93100 LOGTEXT=DISP DIST 52
93101 LOGTEXT=DISP DIST 52
93102 LOGTEXT=DISP DIST 51
93103 LOGTEXT=DISP DIST 51
93140 LOGTEXT=DISP IDHS EOC
93141 LOGTEXT=DISP IDHS
Next go into the ProScan Favorites editor and click on the indented line of the trunked system. In my case it's "Indianapolis Department Of Public Safety

Click "Get Clipboard"

I set the Delimiter to be " LOGTEXT=" (There is a space before the L)
Sometimes you need to click the "Get From Clipboard Everything" button for it to reload.
Change the column names so the "Unit ID" is in the column with the numbers and the "Chan Name" is in the column with the names.

Click import and now you have UIDs imported into that trunking system. Save and then write to scanner.
You'll need to do this for each of the trunked systems you want to add UIDs to.
Let us know if you're OK after these steps.
