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.
Just tried it, that didn't work.
There are two blockchains. The one that has my balance, and a new one. Luckily, my balance was relatively small as I sold a lot of it back in June.
