i get :wub: of unspecified errors

[merlin19]

so i decided to play Medieval once again, and happened that whenever I try to start Campaign with Teutonic order game encounters unspecified error
i started campaign with othe factions and there was no problem with that but i mostly wanted to play with Teutons

when I downloaded MOS for my Third age same thing happened but now I couldnt play anything
same continued when trying Dominion of sword but earlier i was able to choose difficulties and whatnot- and crash happened only when starting campaign, now crash happened immiatedly after picking faction
custom battles were ok this time though

Lets' slow down a bit.

If you are having a crash after selecting a specific faction and then clicking start the reason is usually an invalid entry for that faction in descr_win_conditions.txt. To test that make a copy of that file for back up and then delete the content of the orginal file, save and start the game. You will find that file in the ...\data\world\maps\campaign\imperial_campaign folder of the mod you want to play.
