Ok check all of your folders for any file with _0, _1, _0_0 anything that is _ and then a number. Or there might be a file in Exports that is messing it up. Delete everything from Exports, but do not empty the recycle bin. Then start up FH again and see if it crashes. If it doesn't, then there was a file in Exports that was making it crash. If it does, go to the recycle bin and Restore Everything. Then try other folders like my_objects, deleting everything in there + then not empty the recycle bin. Try FH again + if it doesn't crash it was a file in that folder. If it does crash restore everything from the recycle bin. Hopefully you can find the file that was making it crash.
