Okay that is helping, In the folder users>name>AppData>Roaming> Bitcoin
I have a Wallet and it says it's a Gom Media File (.dat) 80KB. Is this the file I save then uninstall everything else and rerun the exe. then put this file in there?
Close Bitcoin-qt (not only to system tray)
Make backup of users>name>AppData>Roaming> Bitcoin folder
Keep wallet.dat, and delete all other files and sub directories.
Run Bitcoin-qt and wait for the blockchain to download again, you should not get stuck again at block 268351 of 272832
