Just reposting here from technical support forum a post by one other guy and me:
"I buy today BoA for dowload in ageod,i install the game and play correct,but when i install the last patch the game crash in first turn
Regional adjancent mismatch is the text
i send mail to ageod support
Sorry for my bad english and thx"
"Same here..
I went back to BoA because I was sick of restarting the campaigs in AACW and NCP for the nth time after a patch fixes one bug and introduces 5 more everytime.So I figured that after all those years BoA would be patched and playable...guess I was wrong.I tried reinstalling twice with 1.13, 1.13a and 1.13d, but no luck. Time to go back to playing Panzer Campains again..."
