Another trick would be going to the LT game folder itself and delete Bary.SPF. (works with any file actually)I use to have this issue on an old PC with permission issues. (A virus modified what levels of access can do what or your not he admin of said PC, that or an unknown factor is at work.)
LT game folder is at "C:\Games\OGP\La Tale" unless you intentionally changed the install directory during installation.
