Question : PLESK parent paths

Ok not sure why this would affect anything but I set in iis to allow all sites to use parent paths. After that my plesk control panel no longer works just gives me a 404 error. But all the sites are working ect. I ran a repair on plesk but that didnt help. Its just acting like there are no files to load or something anyone have any hints?

Ill update as I play around to get it up and working.
Thanks
