Trouble Installing War Craft III.

[Afterlife]

This application has encountered a critical error
FATAL ERROR!

Program: C:\Program Files\Warcraft III\war.exe
Exception: 0xC000005(ACCESS_VIOLATION) at 001b:73FA93E0

The instruction at '0x73FA93E0' references memory at '0x73FA93E0'.
The memory could not be 'read'.

Press OK to terminate this application.

This is what i get everytime i try and run WC3.

Ive uninstalled, reinstalled (im using the original at the momment).
Everytime i install and uninstall delete the directory and any other remainding files.

The game boots up fine and i get the intro movie but after that i get that error again, and then i get a gay MSXP error send report.

The game used to work fine, I hadnt played in a few months and decided i wanted to play again.

Could anyone please tell me what i am doing wrong, or how to fix this error?
