Maplestory and Compatibility?

I just got a laptop and it has WindowsVista Premium 64-bit. I have SP1 and i installed SP2. After installing all my updates and everything when i try to run Maplestory it gives me a "Windows cannot run this due to compatibility issues". Anyone else have/had this problem and can help me out?

Edit-I also get hackshield error 4

Never got that before, but have you tried running it in compatibility mode?

Also some things to try....update DirectX and video card drivers. Make sure you're running maple as an administrator.

I figured it out. You have to run Maple in XP compatibility then delete the hackshield update folder then run HSupdate.exe to recreate to allow compatibility.
