Glad I could help.

Can confirm the resolution - hopefully Taleworlds(and the Brytenwalda team) keep patching and GoG gets on top of the releases.

@maramot or anyone who's patched it via the links he listed- I jumped through the loop to get the patch onto my gog version of the game, but I'm getting the message telling me it is running in the trial version. I'm assuming there's a way to avoid this, but I don't know the trick. I just installed the patch into my GOG games>Mount&Blade Warband folder. Then I said yes when it asked if I wanted to replace the files. I'm assuming I probably should have said no somewhere along the way, but I don't know where.

Where you able to avoid this? If so, how?

EDIT: I figured it out. Nevermind.
