A very strange phenomenon: suddenly Kontakt 2 will not load Stradivari anymore, neither standalone, nor as VSTi in Cubase 4. Message: "The library you're trying to load from does not seem to be registered properly. The patch cannot be loaded." It worked perfectly before, I did not make any changes to my system.
Oddest thing is: I've got two seperate installs of XP pro sp2 and everything else and it still works ok in the second install!!! The library is installed on a seperate partition which is used by both installs.
Reinstalling Kontakt or Stradivari does not help. The strad loads OK in Kontakt Player.
