Hey DGB folks, when I try to send any amount of DGB to another wallet address I get the following message.

"The transaction was rejected! This might happen if some of the coins in your wallet were already spend, such as if you used a copy of wallet.dat and coins were spent in the copy but not marked as spent here."

I have 700000 coins in my wallet and when I try to send even 10000 of them this message pops up. I dont get it. I am running the windows wallet x64 version.
