That should cause a problem. I have my Civ4:BTS install on drive C: and the BAT Mod on drive D: under My Documents\My Games etc...I have now BAT Mod after BUG and I have more crashes,problems with loads 'fatal error'.I use Windows 7 32 b.Maybe because BTS is installled in drive G,other parts,assets and saves are in drive C in 'my documents'?
Will make a screen shot when will be next crash,is something with file allocation.User name is with english characters,and Bat Mod is in 'my documents,my games,MODS,BAT Mod 4.1'.That should cause a problem. I have my Civ4:BTS install on drive C: and the BAT Mod on drive D: under My Documents\My Games etc...
Do you have any non English characters in your user name? That will definitely cause a problem.
Also, you haven't renamed the BAT Mod folder to something else have you? That will cause a fatal error.
Please post a screen shot so I can see the error message.
No changes in profile.Still 4 GB DDR3.How much RAM do you have in your machine?
Resolution maybe is the problem,was a message in a crash about resolution,to decrease,I use 2048x1152.The game is unplayable,crash after crash using advisors,loads and more.Will use again BUG after my map in progress,ALT+S(signs on the map) is enough for me.How much RAM do you have in your machine?
