I'm trying to get my wallet.dat data back and everytime the rescan is almost complete, I get this error message.

I deleted everything and downloaded the dmg file again and them replaced the wallet from a backup and I'm still getting this message.

At this point, I want to use Blockchain and just want to figure out how to get my BTC out of this wallet.

Can anyone help me please?
