We have run dozens of other successful pools. Yes, there was an issue with the MINT pool. If you remember correctly, every (MINT)pool had an issue and the wallet was updated 3 times in a 1 week span. The wallet was not built correctly and would cause corrupt blkindex files, resulting in forks. The old server was readily available to cash out, and your account was never "deleted".
I was using the last server, when I noticed it will close in 2 days I tried to withdraw but nothing happened then I lowered auto pay out to the quantity I had and nothing happened. Now I could log in after a password reset and the Mintcoin page seems to be rewritten for the Deltacoin, there are 0 coins now and my wallet still in 0.
