still same not help, i was do like your instruction but still error ? i dont know I dont know what I should do 
Try this, move your wallet.dat to your desktop and delete everything else in roaming folder
So it wil start with a new wallet.dat
If that works you have a corrupted wallet.dat
If that also doesnt work redownload the wallet
Let me know how this works for you
if im download new wallet what happen my balance in prvious wallet ?
