Problems with version 9.1

[HcK]

Hi,

I have a Acer 7560G running Win7, game(s) are installed on a SSD. Since upgrading to 9.1 I have started to get a lot of crashes ("Program has stopped working, Windows is looking for a solution"), as far as I can tell only during the campaign repair screen or the campaign support unit purchase screen (and the map editor opened from there).

I installed the 9.1 by making a copy of the game directory of version 8.0 and installing 9.1 there. Did this for the previous two upgrades, too, and didn't get any crashing problems then.

I do have custom OOBs and use them in the campaign I continued after upgrading to 9.1.

Anybody else get a lot of crashes? Are the custom OOBs to blame?
