Startup slow and errorrs

Every time I start ManyCam Studio (7.9.0.52), it gives a warning “an unknown error occurred” please restart computer.
But ignoring that, it will startup up, but is frozen for about 2-3 minutes, then seems to work OK.

One cannot even dismiss he error pop-up for a minute or so.

Why, what’s wrong, how to fix?
(Are there updates to the V7 versions?)
