I suggested this course of action (as a temporary work-around) over a week ago.
Since WA 5.623 and the plug-in works on XP, there may be a configuration error or other plug-in problem on your Win 7 system.
Why wont you submit the "One for Nunz" report of your Win 7 system (which allows people here to better be able to help you) which was requested and you said you have? Or a current one since you have made changes since then.
If you don't trust us to see the report or can't be bothered to submit it, then maybe you should seek private help.
