I was trying to play Subspace / Continuum after a very long time tonight and i had the same problem you guys were talking about in the other posts. Continuum won't load and crss eating lots of cpu and etc etc etc Well... First of all, as far as i can see, it has nothing to do with any other program but just with Windows XP SP2 (access rights) Here is the way to play until developers can get a "more elegant" solution. 1) Install Continuum under an "administrator rights" account. DONT RUN IT AFTER INSTALL! 2) Share the installation directory with "change rights for ppl in network" (it will apply to other users in the computer too) 3) Log in with some other "limitted rights" account and play the game as you always did in the past. Of course if you are not using "simple share" you could (instead of share the installation directory) give "change rights" to the limitted account you plan to use to play the game in that directory. It tooks me some time to realize what was going on, but when i remembered that Subspace / Continuum is in fact a wild animal from the past i came to this solution that i think will be satisfactory for most users until our christmas gifts PS: There is just one absolute truth about windows: DONT MESS WITH DIRECTX! NEVER!
