Same here. Renamed my "Dark Age of Camelot" folder (used to play Uthgard) to "Dark Age of Camelot_Uth", and re-installed a fresh "Dark Age of Camelot". This fixed the crash on loading screen issue for me.
Coming from Uthgard too. I did not create a new folder (don't expect to play uthgard for now). Game crashed on loading screen. I runned camelot.exe. Then runned phoenix.exe again and now it works fine.
