Directly after the cutscenes, all original missions crash the game with the error 0xc0000005. This is on every team and every mission, however Skirmish, LAN and Mercenary missions are fine.
I'm running Windows XP SP3 on a Notebook Laptop with an Intel Celeron single core 2.6GHz processor, a SiS AGP Architecture GPU (128MB of VRAM) and 512MB of RAM (This is my nostalgic gaming PC)
It also has 64MB of system memory, if that helps.
If more information of the error is needed, I can send screenshots of the error via Email.
I have already emailed Gruntmods support and they directed me here.
Any help is greatly appreciated!
