Problem with igdumd32.dll

Hey, 

I think the Mass Effect games hate me, or something. It took forever to get ME1 (kinda) working properly on my computer and now that I have finally finished it, I am having issues with ME2. The game starts, and lets me view some of the intro, to the point where I need to get Joker, but then it freezes and crashes. I get the following error:

As far as I could tell the igdumd32.dll is the problem but I couldn't find a solution for that. All my drivers are up to date, and I found one solution that said I should try unregistering and reregistering the dll (whatever that meant) but that didn't work, b/c Windows won't let me b/c it says the igdumd32 isn't a dll. (It exists twice on my laptop, no idea if that is normal). 

I tried reinstalling it and rebooting after the install, I tried running as admin, didn't work. I also imported my ME1 files, I haven't tried deleting them, b/c it didn't feel like the error was there, but I can try that as well, if someone thinks that might help. 

I don't think it is a problem of my Laptop being to old (although I don't want to rule that out, b/c it is definately not anything fancy). It runs on Win 7, with Intel HD Graphics and NVIDIA GeForce GT 630M. CPU is/are four Intel Core i5-2450M @2.50 GHz , 4 GB RAM and enough diskspace. 

I'd be really greatfull for some help!
