Did this. Result:

"Database corrupted" And then asks to restart.

Deleted all local data, moved client to new directory and started fresh with backup wallet.  Result: crashed, with same message.

Rinse and repeat...Deleted all local data. Will restore wallet later IF I can get block chain to sync. 

I have seen other posts about this...am thinking about moving back down to 0.8. Have transactions hanging in the ether; I know they should be confirmed when I sync but this still makes me anxious.
