Not sure what happened, but, MP has been crashing as soon as I go into the plugin
Maybe try to use the default skin to see if this still happens. I'm no expert, but it looks like your skin may be trying to call a property that Moving-Pictures does not offer (although one would think this could be handled a bit better if that is the case).
I think this issue is corrected in the upcoming 0.7.1. I will PM you with details on helping test if you're willing to help us verify the fix.
