Well, there is a more tech centered forum on this board, maybe you should check it there, too. This is called: Apothecary

Also, you supplied very little information about your problem. Most of the times CTDs are caused by bad drivers. So update your drivers if you have changed anything since used the game before (or changed machines, etc) With some video drivers it is NOT the latest that works, but I am unsure which ones are these (NVIDIA?). I am sorry I am not particulary good at tech things with computer.

Change your drivers, check other threads, search the forum and be patient.

Welcome to the Guild and have fun!
