It seems like liberty reserve is having a delay on the withdraw and could take up to 3 - 5 days for your funds to show on your account balance. But your transfer has been processed.

just spoke to magicaltux on the irc channel and i think everyone is on a long wait for liberty reserve withdrawal.he said it will take few more days before the problem is resolved, so i advice do not make any more withdrawal via liberty reserve.i wish i saw this before making any withdrawal...i think i trusted mtgox too much.

I told him to reverse my withdrawal and he quoted they do not have tools for that yet...too bad ordinary bitcoins7.com has that function
