I'm experiencing the same problem. been using MC since build 14, never had an issue before. Recently built new pc after a major hard drive malfunction and installed MC from library backup. Was initially okay but then started crashing. Runs for a minute or so, then just shuts itself off with no warning.
Uninstalled and started again without the library backup. Stated with a fresh slate and set up a new import. Is initially fine, but then gets to a certain point and crashes out.
Figure it must be a bad file that it is trying to import, or has imported and is now causing it to crash. I recovered the media from the dodgy hard drive, so quite likely that some files have become corrupted. If this if the case, how do I identify the offending file? I've followed your instuctions and downloaded a system log, but it won't let me attach it, as the file is too large!?
