Basically the same problem as this guy:
http://www.toontrack.com/forum/tm.aspx?m=90596
I’m running the following:
Mac Pro Dual Quad Core 2.66 GigHz, 16 Gig Ram, 4 Terabytes Hd, OSX 10.6.2. Core Audio
Logic 9.0.2.
My problem is not with the host but simply just opening up toontrack solo and selecting EZ Drummer
Here are some screen messages:
I did try and install it multiple times from the disc. After receiving my serial numbers from toontrack, I was able to authorize it but it still wasn’t working. So I download it again and got the same result.
I own every single product offered by Toontrack. I really wanted this one to work. Thanks.
Since I can only embed one picture at a time, I am posting the second failure image on my second post.
