Okay 400...have u try do dump the cd in to the harddrive and run the setup.exe from there?
New:er safedisc like 2.XX don't contains safedisc protected .dll files.
I'll only have been seing one setup files that's are safedisc protected. that's is Operation Flashpoint english version. And they have releas crack for the setup file. So if Dungeon Siege is safedisc protected. Some one should alredy have reales a fix. And the game has been out for a verylong time. Like a half year or more.
