I just purchased the V-collection, and have the same experience. Paid for it on the 3rd, and Support has been very slow to help me resolve the issue, even after opening a support ticket.
I finally found all the downloads on my own, only to realize that the V-Collection installer doesn't even load the latest versions. Had to go through one by one and update them all. After that, don't have sound from SEM, Analog Lab, Analog Laboratory, and Wurlitzer. They generate no sound, or just lock up and have to be closed with Force Quit.
Not good. What did I get myself into? Should I just reverse my charges now and go on my way?
