Thanks for all the support though. In the meantime I am starting all over on a new wallet and mining... If anyone want to sell me some DGB for a good price that will be appreciated!
I did that, but I am really sure my wallet.dat is corrupted really bad. Since a generated "new" wallet is about 112 KByte, but the one I have is way smaller in filesize No good... I can upload the wallet if one wants to try to fix it, but learned the hard way to make backups at time of installing a new wallet...
It also may be possible to restore to the last system restore point.
Try using a program called ShadowExplorer, it allows you to browse previous file versions, hopefully you can find an old working version.
Goodluck
