Hello there, I am the new one

At first I want to say that you did a really great job on modding TS. DTA brings back the old C&C 1 feelings and combines it with great skirmish action (in high resolution). There's so much love in each little detail, it's amazing. Thanks for that wonderful mod!

But now to my problem:
The mod crashes in skirmish. I couldn't find out if theres a specific thing happening, which causes the game to crash - so it just seems random. This is why I saved my next game and when I tried to load it again, there's the crash message again.
It says Dawn of the Tiberium Age has encountered an internal error and is not able to go on normally. Please report to www.ppmsite.com .....

My game version is TS 2.03 german
DTA is 1.09
I have Windows Vista 64bit
Geforce 8600M GS (actual drivers)

Maybe someone could help.

Edit: some additional info
it's all (both TS and DTA) a fresh install
