Content not loading in HS1.6

Hi, I’m using CA 6.0.7 and when I doubleclick a preset after installing the HS1.6 update nothing happens. Or when I try to open one via rightclicking and “opening a program” in e.g. slot 1 I get a “Loading Program Failed” message. I got the same problem with HSSE 1.6 but on the edit page it says: “Please make sure that the required VST sound instrument set is correctly installed!” Everything was fine prior to the update.
Can anyone relate to this and help me? I don’t wanna reinstall 1.5…
