Looks like were out of luck then. Our version is 1.208.2.1 from circa 2007/12/07. I assume we can't just replace this one file with the latest version? We simply cannot move to 7.1 at this point. We have some substantial kernel mods that would need to be ported and tested in the 7.1 code base and there simply isn't time for that.
