Invalid Playlist Item Class: Cart

I get the above error message when I try to load a cart set in one of the studios - I made the sets in the office, and they load fine on the computers in there, but no luck in the studio - apologies if this has been flagged already - couldn’t find a relevant topic though.

any help would be much appreciated


This is most likely because you’re trying to open a file which as created by a newer version of mAirList. Can you check the version numbers in the office and in the studio please?

thanks torben! muchly appreciated - that was the exact problem and its all fixed now.
