the state of some kontakt instances cannot be recalled correctly / future application needed

Hi,

I updated Komplete this morning and all went well for a couple of hours.

Then I tried to load an Ableton set and I get the "the state of some Kontakt instances cannot be recalled correctly". The plugins are blank, no instruments/ presets loaded. Then get the "future application needed" error.

My standalone version (now 6.7.1) does not match my plugin version (still 6.6.1).

I'm on Windows. Any idea what I could do?

Thanks a lot,

Jf
