Post any questions, problems or concerns in the official thread from now on, please. (I get emailed when people post there, so I'll be updated that way as well)
About your error. If it's saying "Debug 0,0", then that should have been fixed a while ago. If it "needs to close" because it "encountered a problem", then perhaps you can try to duplicate this with a level made entirely from STOCK media, then send me the .fpm of that level and I'll take a look to see if it happens on my machine. In order to effectively find out what the cause of your problem is, I need to be able to see it happen for myself.
There may be a chance that it's just your computer, too, though let's hope not.
The one and only,
