Can't Get Geist to work :/
Where can I get the Computer Music version?

I found a solution
Make an account at FXpansion website and go to the link http://www.fxpansion.com/geistlitecm, then insert the code CM83671232 and they will give you a unique serial number
Login to downloads and you'll find a download link for Geist lite

But that's for GeistLite... Not GeistCM
It adds a plugin called Geist Lite, while the track looks for a plugin called GeistCM
