Please help. I had a wallet that I created in 2014. I deleted the qt wallet several years ago. I downloaded the latest version of the qt wallet and imported my wallet file. My DGB is there and it shows my available balance. However, I can not click on send available balance nor can I send a small amount of DGB.  It shows my available balance of over 1800+ DGB but even if I try to send 100 DGB my wallet says that  don't have enough. Does anyone have any suggestions?
