I recently purchased "Analog Modeling Suite" via a bundle from Xchange. I registered and downloaded the application, however my Mac will not allow me to install it due to an error that says "The App's authorization has been revoked" with an explanation that says:

"There may be a problem with this app. Although the app was signed by an identified developer, the certificate for the app has been revoked, and it cannot be opened.

Check with the Mac App Store or the software developer to see whether there is an updated version of this app."

Any help appreciated.
