Vista - Metal of Honor Spearhead

Hello,
I have been trying to play Metal of Honor Spearhead and I cannot get the game to load nor can I get Breakthrough to work either. However Allied Assault runs fine. When trying to run spearhead all i get is the gray screen and it says that Spearhead has stopped working and give me the following error message.

My computer specs are
500watt Powersuppply
3.0ghz intel processor
4 gigs of ram
ATI HD2600 video card with latest drivers
Windows VISTA Home Premium 32bit

I also have Call of duty, call of duty united offensive and Call of duty 2 and they all run fine as well as all my other games. Just can't Spearhead or Breakthrought to work at all. I have tried to launch using compatibility mode and that does not work either. I have also tried run as administrator and no go. Anyone one have any ideas?

When u tried compatability mode which one did u use. For some games running in XP mode wont work either so you have to keep going and try each one. I've had to run a game in Windows 95 compatability even thought the game officially only runs on XP. Go figure.

I have both addons running fine but it was so long ago that I installed it I cant remember if I had any problems or not. If I get chance I'll have a go at reinstalling them and seeing if anything happens.

I tried all of the compatibility modes XP, 2000, 98 and ME with no luck. If you are running a ATI card I found that reverting back to the 8.6 drivers worked for me and it has worked for others and it worked for me. Try it and see what happens. AIT told me that this is going to be fixed in a future driver release but you know how that goes.

Let me know if this works for you.

Glad you got it sorted. I don't actually play MoH anymore. I loved the whole series and then one day I played Call of Duty and I've never gone back!
