Newbie Please hekp

Hopefully someone can help me before i go insane trying to sort out this problem.
I have downloaded Cubase El 8 i got with my Zoom R24.
Everything seems to have downloaded but the Synth is the only plug in that is listed in the VST instruments.
I’ve tried changing the file path but cannot get Groove Agent to load.
Im not very good with computers & all this talk of plug ins & file paths is stressing me out.
I just want to make music, not become a computer genius!!!
Any help would be much appreciated.

first try a re-install.
