Thanks. It does not have a repair wallet in the menu. I tried to enter it at the console command line.
Do you know the exact syntax?
Close the wallet, make a backup of the wallet.dat, put in the chesscoin.conf file "reservebalance=9999999", restart the daemon or qt with flag "-rescan". That's going to take a long time, but unspent outputs should be recovered that way.
Thanks. I will try that. Incidentally, I kept the old blockchain folder, just relabelled it so the wallet would read it instead of the new one. I see my coins there now.
I originally was having problems because it wasn't syncing.
