I am running the new wallet for Windows but it seems to crash around every 5 days.
I am usually able to restart the wallet but this time I got the error:

  Exception: St13runtime_error
  CDB() : can't open database file wallet.dat, error 16

and it's stuck and won't sync.

I tried replacing the 1337.conf file with the new one but that didn't solve the problem.
It's still stuck trying to sync.

I don't know if I should replace the wallet.dat file from a backup because there are
3 staking payouts with 3, 2, 1 confirmations respectively and I'd rather not lose those.

What do I do?
