Company of Heroes crashing

Alright, so I got this game a while ago, but I cant play it for more than 20 minutes without it crashing. I mean, this game crashes ALL the time up to the point where I can not enjoy this amazing game. I'm on the first campaign - the mission where you have to capture the town hall, and I just can not play it at all. Is it because I'm launching the game without the disk? Anyone else have these issues?

Finally! Somebody else who has the same problem as me! I'm in the same position as you my friend, except that it crashes occasionally, not frequently - both MP and SP. I've made a thread like this ages ago with the exact same title, but nobody answered me. Hopefully someone will help us out.

Is the game updated to the latest patch?

Thank you, I'll try setting the textures down from Ultra. : )
