Cannot install Course Press Pro after sign up

I have just signed up for Course Press Pro at $19 a month and cannot install the plug in !
I have installed the WPMU DEV dashboard but the Course Press Plugin does not appear (screenshot added)
Can you please advise me on what I am doing wrong?
I also cannot work out how to install any of your themes, plus I have not received any emails confirming my subscription ?

thanks,
Vanya
