if you have synced wallet you can try this command line key one by one until issue will be resolved (you must backup your "wallet.dat" before):
-rescan
-reindex
-salvagewallet
I tried those commands and it said method not found. I see the transaction on the block explorer and I still have the same address, not sure why it isn't working.
I tried these and my wallet still has 0 Sync. When I first downloaded a wallet I sent Sync to it but couldnt get it to connect to the network so I saved the wallet.dat file directly from the AppData/Roaming/Sync folder and then downloaded the newest version of the wallet. I still can't seem to recover this backup and would appreciate anyone that could help me.
direct inet-connection or behind a router ?
