SSI showing "Not installed" in Plesk

[logan@jatol]

SSI is broke on my new Plesk 7.6.1 (Windows 2003 - all patches) now. I just got this server a few weeks ago, and even though SSH is turned on in Web Extensions, and .shtml and .shtm are listed with correct references in the domains (and will parse just fine) it is grayed out as "Not Installed" under Plesk. I even removed it from the Add/Remove Components, rebooted the whole server, and then added them back with another reboot w/o any luck. They stil parse, you can map them, and they parse just fine just you can't select the option in Plesk. Any help would be great, but otherwise I have used up all my resources (including this forum) and will just wait till 7.6.2 incase it's an odd issue in 7.6.1?
