Please help! I'm Using TES construction set on Oblivion GOTY deluxe from steam, when I start it up I get the message "unable to load CTL files." does the CS not work with the steam version? Also I can't update the CS, it tells me it cant find the 'Old File' I'm a major modder for the fallout series, but before Skyrim comes out i would like to do a little oblivion.
