Dear God, Please Help Me.....

Cannot get streaming MLB TV to work in WMP11 in Vista.
No, I can't see it in windows update list or control panel so can't uninstall it. no I can't download and reinstall as my version is newer than the one you can download, no everything else works fine, but in Tools->options->Network

THERE ARE NO PROTOCOLS listed in the "streaming proxy settings" box at the bottom. I've ticked and unticked all the protocols at the top and the multicast thing, but there is nothing in the bottom box, hence I cannot "configure" http to be "auto detect" or "browser" as nothing is there

how is it possible this box is empty
how can i get http back in there


PLEASE PLEASE PLEASE PLEASE HELP ME
AAARRRGGGGGHHHHHHHHHH
