Adobe After Effects CS3 Crash in Vista

I've installed and re installed After Effects CS3 Trial about 5 times now and it keeps crashing when the splash screen pops up. The message "Adobe After Effects CS3 has stopped working." I found that the message comes up when its initializing Media Core. Here is the report from vista about the App Crash.

Please help!

It always crashes when its initializing the media core, and I've looked at few previous reports from windows and the fault module has been changing, its been StackHash_8984, StackHash_d742, and StackHash_acaf. With other extensions showing up only once.

I've also received errors reports saying that "ir32_32.dll_unloaded" was the fault module.

I've removed my other adobe programs off my computer and used Clean Script, but it still crashes at the same point.
