Crashes on Opening

On my main computer 15b2 crashes when ever i try to load a project
and on my laptop it crashes on splash screen
Both computers are running windows 10, Main Rig is fully upto date, laptop hasn't had the latest updates yet.
foolishly i forgot to backup the database before updating it
so i got a lot of half finished projects that i can't get to at the moment
Any help would be appreciated!
Main Rig:
AMD FX-8350 8core 4ghz(clocked to 4.2ghz)
32gb ram DDR3
GTX1060 6gb
Laptop:
i7-4712mq @ 2.30base(turbos to 3.30ghz)
8gb so-dimm ddr3
GTX 940m 2gb
