Delete everything in your appdata folder except the wallet.dat file.
Download the updated client from the OP.
DO NOT ADD ANY NODES AT ALL
Let it sync, if it stalls or has problems, close it and reopen it.
If you are missing coins go to the console and type repairwallet
Wait a minute or so and close the wallet.
Reopen it and all should be fine.
TO BE CLEAR DO NOT ADD ANY NODES, INCLUDING THE ONES IN THE OP.
