I can't launch the latest update, now it just 'unexpectedly quits' before loading. I tried uninstalling and reinstalling a couple of the past versions, but the directory folder was never created. Strangely, the 0.7.2 version did actually launch, with the right wallet contents, but still no directory folder. When I tried going back to the most recent and the most recently successful version.. it still doesn't work. I even tried creating the folder myself before an install but it still didn't work. ANy suggestions?
