Hey guys,
I'm going to download a few trainers & see if that can increase my nano catalyst back to the value it should be. I hope that helps because the v1.2 patch doesn't seem to help me yet.
I'll inform you guys which one is better form GCW.

~By the way, this is my autoexec.cfg.

Someone's already suggested just memory editing your nano catalyst back. It works fine but it isn't really a valid solution for everyone (particularly for those who don't know how to memory edit).

What difficulty level you playing on? Maybe changing the dificulty level in game to see if that works?

g_difficultyLevel =

Yours is blank. Cant find mine now seems to have disapeared after last patch

I played with Normal Difficulty but changes the AI behaviour to PostHuman's.
Till now, I still can't find a trainer that can manually add the value of nano catalyst.
