I am having new problems with system "freeze ups" when flying PMDG aircraft with REX (Real Environment Extreme), which I recently installed. The FS screen just freezes with no keyboard or mouse function. I am using FS9, PMDG 737NG with all the updates and 747-400, 747F Queen of the Skies. Window XP. It was suggested in a forum by Peter Dawson that reinstalling all of the PMDG products might correct the problem. It is quite a procedure to do the reinstall. Would you recommend it or is there another option?Thanks, Steve Canham

looks like PMDG + REX is to much for your computer maybe you can try putting in some lower graphics in FS9 if that doesnt work you might try to de-install REX and if that doesnt work your best option is to re-install PMDG stuffdid you already tried the FS9 repair tool?Rik.

Sounds an awful lot like CPU or GPU overheat to me... I'd check your temps while FSX is running.
