You guessed it from the the title, re downloaded the game (Through Steam) as i fancied a bit of DoW.
Installation went through fine, loaded up, Custom SoloMP, CTD, tried again, CTD, constantly no matter what i do i get CTD.
I never had this issue when i first had the game installed, never a problem at all.
I've tried the standard 'Verify game files' 'Deleted all local files in - Documents/my games/Dawn of war III
If any body has some ideas, that would be great!
