Can't Find GA3 in Cubase 7.5 on my Mac Book Pro, please help

Hi Guys

I have recently changed my machine to a Mac Book Pro from windows.

I have installed Cubase 7.5, and I have installed Groove Agent 3, I have also installed GA as per the Mac full install patch on the Steinberg site, and then the update patch.

So I now have both programs installed on my Mac Book, but when I open Cubase I cant find GA 3 in the midi channels, or in the VST devices drop down.

I can though open GA3 independently, and play the drum patterns, though the sound comes only through the Mac speakers and not via my soundcard which is an Edirol UA5, which is hooked into my monitors.

So my questions are please.

  1. Why can’t I find GA3 in Cubase 7.5

  2. What do I have to do to integrate the two programs within Cubase 7.5

  3. If my GA3 is playing independently, though only through the Mac speakers. How can I remedy this.

I sincerely hope someone can help me with this please, because its starting to drive me mad. I just want to get on with recording.

I really look forward to reading any replies, and I hope you can help me resolve this issue.

Thanks Guys.

Kind Regards
