Changed Platform to Diff Category (launchbox Dead)

[devilchi]

I moved My Mame  Platform to the Arcade Category and Launchbox closed.  Now it reopens with everything blank and closes.  Bigbox still runs fine.  How do I undo this problem? Been setting up launchbox for months and dont want to have to start from scratch.  Any help is appreciated.

*Update* Fixed it.  Somehow the Mame Platform got messed up in the xml as a Category and the Arcade Category was inside it.  Just changed everything in the xml to point in the right direction and its up and running just fine.
