I am running a Mac Pro using El Captain OS X. I currently have Studio One version 2.6 professional installed and running fine. I downloaded the Demo for V.3.0 and it works fine, but when I purchased version 3.0 professional upgrade from the online store, I downloaded it, then registered it, but the Demo version comes up and does not recognize the full version 3.0. When I try to activate it from Presonus it does not recognize the code.
When I try using my Mac Book Pro running El Captain 10.11.1, under the same description as above, the activation screen comes up when I try to load version 3.0 but it does not recognize my username and password, even though I am in the "my persons website.
I put in a trouble ticket two days ago but have no response from Personus. So I thought I would try this.
