The version I have i the pro version with video mixing support. I got this program as a gift on my pc. I can still use it even if I dont upgrade. Everytime I try yo upgrade it opens chrome in a new window and says access denied. I saw the free version upgrade on the mixvibes site, but Im afraid I wont be able to use it as the pro version
Is chrome your default browser? If yes, try changing the default to another browser and see if that helps with the "access denied" error.
