RGSS stopped function

[mamachi]

I just got Windows 7 on my pc and now I cant play my rpg games any more. I started Millenium 3 and got the message "RGSS stopped Function" and I dont know what to do. I copied the .dll file to windows/system32 directory but with no luck.
It also say stackhash 2264.

I am afraid it is all my aldora and laxius games so I really hope there is a technical genie here.
Please help

I do have 7 and I can run them so it should be something else... not sure what, though

At last I found out what was wrong.
Thanx Indy.
It was the DEP (Data Execution Prevention).

All my Aldorlea games run again. Happy happy day
