Letting it "run" I just got an incoming transaction from February 2018... But I am unable to see the wallet at all. (I already tried #18 for the record) and salvage wallet, and upgrade wallet format - which is right before I received the transaction....?
There may be corruption of system files on the disk C:\.
Start a new wallet via a shortcut with a different location and moving in the it your file wallet.dat
