My file version (184.108.40.206246) hasn't changed, but I do wonder about all the hot fixes GBX has been putting out, and how that could affect us.
As a result, I'm sticking with the Editor and running in offline mode as much as possible.

Your Borderlands2 Application file version (Borderlands2.exe) needs to be the same as the Trainer version, as you probably know.
For me, that file is located at:
C:\Program Files (x86)\Steam\steamapps\common\Borderlands 2\Binaries\Win32\Borderlands2
That last Borderlands2 is the .exe file. You can hover your mouse over it, or right click it and then click properties, in order to see the file version (which is different from the product version, by the way).
