Recover 'attempts' to locate the temp files, etc that were in use during the previous session. Sometimes works, sometimes doesn't. I've found no reason not to try it. If it doesn't work just re-open the file, which is your only other option anyway. If it does appear to work, I 'save as' another name just in case there is some glitch that shows up later.

Default refers to the program starting over, where you set up the soundcard again, not 'my settings' (which I think BiaB does). At least that is my experience with it. I haven't had a crash (except during Beta testing sessions) in quite a while.

Have you added a new plugin? This is one of the most likely causes of new problems .. either that or a disk starting to wear out and show errors. For example temp files being written to a bad sector, etc. You could scan the disk for errors and see what it reports.

I do not work here, but the benefits are still awesome
