4. KNOWN ISSUES

4.1 Game crashes into Blue Screen

The game may show instability on systems with 1Gb RAM, Windows XP, and anti-virus software installed.
Please expand your RAM, uninstall anti-virus software or install Windows Vista to solve the problem.


You do realize saying it works with windows xp in the system requirements on the box then saying in the after install readme that it doesn't , please buy vista to play the game could be interpreted as a fraudulent claim ? The released System requirements are a legal guarantee of performance.....so which is it ?

This is a very rare issue, and you don't need to worry about it. The game runs perfect on XP.

I wouldn't go as far as to say perfect......hopefully once the fix to the metaboli fix is finally done it will stop locking up especially in the editor...
