Downloaded the Studio One v2 demo tonight. Install failed. The message says, "Studio One 2.app" can't be opened. You should move it to the Trash". Clicking on the "?" reveals this in the "Help" dialog: "The apps authorization has been revoked Although this app was signed by an identified developer, the certificate for this app has been revoked. There may be a problem with it. The app cannot be opened." I've never seen this before, and I'm baffled by it. Has any one else seen it? I cannot find anything on the Presonus site about it. Any help is greatly appreciated. BTW - I'm running 10.7.4 on a 2011 2.2Ghz Intel Quad I7 w/ 8GB of RAM.
