(.632) Insistent System Crash

[miruim]

I played this game for 3 days and it always ran perfectly.

This morning my brother-in-law was playing and the game crashed. No one cared because it was the first time. (Total system crash.)

This evening I was playing (big battle, helping my kingdom's army in a 15 vs 15 battle) and it crashed again. (Again system crash.) Again I didn't really care althought I realsed this game crashed sometimes too.

I restart and load my save game. Same battle. Same crash but it took a little longer after battle starts to crash.

I send the money through PayPal to purchase a serial.

Ten minutes after restarting, I try to create a character and it crashes while I'm distributing points.

As soon as I restart the computer, run M&B and try to create the character again, it crashes.

At this present moment, every time I try to create a character, it crashes the game. I deleted all the savegames just in case that was the problem.

Now I can't even create a character.

Please someone help me...


EDIT: Just in case it helps, just opened up rgl_log.txt and here it is:
