Ok, try to delete all files except wallet.dat in roaming folder. Prior to that copy/backup wallet.dat to some secure place. Then run the wallet qt again, let it sync, wait for sync. Leave your wallet open for longer time unlocked.

I had staking delayed for more than one day once, but after that I got mined coins.

Send me a screenshot...im on the road and not near my computer.....it has to be your connection or OS setup.
