This happened on two independent copies of PD9 on two different computers. Then, just like it went away, it came back on both computers, as I recall via updates.
Now, it's done it again. About half of the free categories are gone. I suppose time will tell if it will just come back too, but you can imagine how annoying this would be. Any project that uses portions of the now missing categories can not play them, so one would loose that part of the project altogether.
Thoughts????
Again, many thanks,
