I'm having the same problem here. I exported the wallet.dat and when i restarted my balance was set to ZERO! How can i get my coins back? the auto-backups don't seem to working and ive lost all transact history. Please help!
could you be more specific in what you've done please ?
Yes I went into File, Backup Wallet .., saved the .dat file and then replaced the current .dat file with a previous auto-saved.dat file. I received an error message about the client not being found and the wallet crashed. I restarted the wallet with a zero balance although the block chain was still synced. I cannot access the private keys now. I may have just burned a masternode.
