Have you done a re-sync on your wallet with the blockchain?
BTW, you do have a backup of your private keys, right?

Don't do anything you're not sure about, especially if it has anything to do with deleting, or reinstalling, etc., etc. There are experts who will help you if needed. The DGB is there, on the blockchain, and if you've got your private keys, there is no doubt that you will be able to "recover" those funds.
And then you'll also have learned a very good lesson that important amounts of DGB are always best managed with the full core wallet . . . but that's for later. Now you need to try a re-sync.
I'm sorry, but I just had to highlight this... No personal offense meant in any way, since this user Bonus has lost/"lost"/'locked-up a pretty decent amount of assets in limbo and you're the only one thus far reacting on it for a few pages; it's just that I'm touched by the amounts of comments meanwhile regarding talk about 'real' robots and prices and stuff... Seriously?
DGB ...
