I have just installed Kontakt 8. I find some of the instruments are greyed out/ not recognized in this version of Kontakt 8 int he loop / one-shots sections. The wave samples also will not load into an instrument when clicked. A dialogue box appears: "the file format is not support or corrupt." Loading Kontakt 8 in Fl Studio doesn't seem to have quite the same issue. The instruments are still greyed out, but individual wave file do load.
Also, loading the same file in Kontakt 7 has no issues. Is there a bug that needs attention with the latest version of Kontakt?
