Ive got myself a bit of a problem. Last night i fired up and sanc my wallet to make sure my mining rewards were coming in. Everything was fine and i left it running over night.

Well windows decided to update over night while my wallet was open. So this morning i fire it back up and the blockchain loads but i get an error openeing my key file.
I think the os updating while the wallet was open messed something up and now i cant access my 1650 bbr..

@crypto_zoidberg, is there any advise or possibility of regaining acess to my coins?
@1blockologist, when i search "corrupted" in the thread i see a post of yours stating that you were getting the same error. Did you fix it? and what did you do to fix it?

Any advice is appreciated. I didnt make a back up.. what is worse is i didnt even do this myself... windows just goes ahead a does whatever it pleases whenever it wants..
