:jail: When I open the player .fla, it works even though I’ve adjusted the xml files asociated with it etc. It publishes to the same folder that website .fla is in.

Then I go to convert the .fla player to a MC so that I can add it into the website timeline, since everything works fine. When I do that then I get these error message, when I ctrl-enter.
