KITAANGEL'S PROFILE

I've been having a bit of a problem recently.
The last time I've used RPG Maker XP, I had Windows XP as my operating system, but recently I've gotten a new computer with windows Vista on it and I installed RMXP on my computer so I could pick up where I last left off.
The problem I'm having is, Vista won't let me run the program at all. I keep getting this error message right away telling me that The program has encountered a problem and must close. Windows is now going to try to find out why. After the short wait it then tells me. Windows found a problem and the program has been closed. It doesn't tell me what, or why, or how I can fix it. I tried running the program as if I were using Xp, or any other version of windows, I've tried running as administrator, but I'm stumped.
Any help available please?

Thanks ;)
