It seems Rob has updated the gridcoin.us back to 2.1.0.7. I downloaded it and was able to sync.

However, I kept getting "wallet.dat corrupt, salvage failed" errors.

I tried all my backup wallets and all with the same error.

Also tried "gridcoin_qt -salvagewallet -rescan -reindex" with no luck.

Anybody has better idea on how to recover the wallet.

I was running 2.1.0.4 earlier. Could that be a problem?

Does anybody have the 2.1.0.4 version so that I could try whether I can recover the wallet?

Your help will be greatly appreciated.
