I was upgraded to Yosemite, due to a a need to erase the current system. Once that happened I was not able to reinstall my two disks EZ DRummer. I went to your site and logged and downloaded easy drummer, as it suggests, and the upgrade. In logic I opened the EZ drummer after authoriztion and find ony pop rock andcocktails.
I had bought and have on my discs: DISK 1–Ez player PR, Claustrophobic,Twisted Kits, Nashville, Drumtracker
Disk 2 Drum kit from Hell, Latin Percussion, Vintage Rock, Jazz, all EZX
