Cannot add or edit content types after installing module media

Hi, After I installed the media module( I tried both versions 7.x-1.3 and 7.x-2) I cannot edit or add content types ! I got that message: "Additional uncaught exception thrown while handling exception.

Original

Sorry for big text! I read about it and people says that can be solved increasing the max_allowed_packet in mysql server ini, but I cannot access the server ini, iti is on a public host server and the administrator cannot ( or don't want to) change it for me. I wonder if it is something to work around for that matter?
Thanks for help!
