Ive purchased the full game plus all three expansionsfrom steam, downloaded and they say theyre installed and i can locate them in my hard drive but they are not showing up in my datafiles in the launcher so i can activate them. In addition they are not listed in my skyrim properties in the steam pane. Ive been on steam forums all day trying to synch everything and have exhausted all the suggestions there, with no progress. Does anybody have some tips or instructions for me? im running windows7 and am not very familiar with this OS.
