LOST 2000 of Omega on Monday! Notification in SouthExchange: "OMEGA seems to be forked. Deposits and withdrawals are disabled until the situation is resolved" What a f...? Sorry
Had the same, but with 517 coins. I've used in the NEW windows wallet (so v0.12.5.1-b31d6d5) the steps below
1. Rescan blockchain files
2. Rebuild Index
3. Recover transactions 1
And recovered my 517 coins. Perhaps this will help you to recover you're 2000 coins ?
