I'm having trouble installing EZ drummer Nashville and I think it's a logic problem.
I have the original ez drummer program installed and it's showing I have about 154mg on the ez drummer interface. Now I'm trying to add the Nashville program . I keep getting an "installation failed" window that says "run post flight script for EZX Nashville". I'm not an expert at any of this but I do have licensed copies of these programs all registered with toontracks. These toontrack programs are older and I used to use them quite successfully when I was running cubase on my laptop. I have updated everything from the toontracks website but still no luck with installing Nashville.

I have an Imac 10.8.2
Any help would be greatly appreciated.
