Due to an unexplainable error (random crashes with "memory something something XXXXXXXXXXX cannot be read and program must be terminated) I need to reinstall the program.

So what are the steps?

Do I Unregister, and then Unistall then Reinstall?

In what order should I go about doing this?

Assume I dont need to bother saving any scenes or settings I made.

Any help appreciated thanks.

Unregister, uninstall, redownload, reinstall.

Unregister through the game directory (there should be a file called Unregister.bat). Run it, and your key will be unregistered.

Run the uninstaller, or use Windows Add/Remove programs to delete the game content.

Redownload the game .exe, reinstall as normal.

Re-register.

Thanks, the steps worked, but I still have that problem.

Is there anyway to totally wipe it off and restart? like removing registry keys? I tried deleteing the whole folder after uninstalling but I couldnt delete it for some reason.

I don't think that error is a problem with the game, inasmuch.

How much virtual memory do you have? How much RAM do you have?

Solved the problem

Turns out I was just LOOONG over due for a defrag.
