PR wont load, just green screen and ctd

[icecreamterror]

Had to move my desktop to another room for a couple of days, and use a small 19" monitor, but now iv returned it to my large monitor it wont load PR.

I just get a flashing green screen with a dark box at the top left and then CTD.

Iv tried opening it up an another window, but just get the following error



This has happened once before, and I had to do a Total reinstall BF2> 1.41> 1.5> PR1/2> PR2/2 to get it working again, really want to avoid having to down load all the patches again!
