Please help!

for some reason when ever I start playin ESF like not even 10 minutes into the game it crashes, and it Windows say's HL has encountered an error and has to close. Please someone help me out here I cant even enjoy the game because it crashes...

Firstly, welcome to the forums....

And secondly *SIGH*, please use the button for such questions before asking. Nevertheless, here you go: Try switching to other video modes, example OpenGL (the most stable for most people). That problem you have stated is very common to Software Mode users. So try switching to different Video modes (ESF > CONFIGURATION > VIDEO > MODES > Switch to OpenGL) with a stable resolution.

Hope this helps.
