XML parse errors can occur if you have a library (either created in Poser 5, or an old Poser 4 library) that has one of the following characters in the name: quote (") apostrophe (') ampersand (&) less than (<) greater than (>) (These may not cause a problem, but may be problem characters) back slash () slash (/) This issue is addressed in our Poser 5 SR1 updater.
