then i had a runtime error message, including something about some Rewire file (i wasn't running any rewired app).
then Live shutdown, but the process was still running in the task manager.
knowing that this would soon result in a windows blue screen, i rebooted.
on opening the lastly saved file, i had just one empty audio track (not even my template). fortunately enough, the original file wasn't corrupted.
but it's not the first time i get a blank file after such a crash, i nearly lost a whole set like this...
and i can't see anything i did that could cause this crash. just closing an already saved project...
