Hi, i've had kind of similar actions. When auto loading Catalyst from startup menu the dongle wasn' t recognised. Quitting and reloading catalyst solved it. Strange and it did not happen always, only in some (unpredictable) occasions.

I found that removing Cat app and reinstall sometimes helps. In one occasion Cat app got corrupted and I had to reinstall because it wouldn't work no more.

So maybe you should try a reinstall????

Good luck
