stay tuned please. New client will be released in the next hours.
Thanks. I started mining DMD yesterday and been having trouble with the wallet and network. Trying to sync from start but it's taking ages. I hope the new client helps.
You can always pool mine (there are now three active pools) while you wait. You don't need a client or synchronization for that.
Anyway, as difficulty increases with price, solo mining may not be a very good option soon, unless you have strong hash power.
