I'm having trouble activating Xamarin.iOS on my mac and PC. I'm logged into my Xamarin account (I have a dev seat on a business account) on Xamarin Studio on my Mac and Xamarin Studio (and VS) on my PC, but those computers refuse to show up in my account computer lists (which is empty). Presumably, because they are not in this list I am unable to use features as I get prompted to 'Please activate Xamarin.iOS'. I've created a fresh account, uninstalled Xamarin software on both machines, and reinstalled the package from my account downloads to no avail. The install instructions imply that being logged in to Xamarin Studio is sufficient to activate and link Xamarin.iOS to my machine, but I may be wrong? I think it is interesting that this is happening on both machines - perhaps there is a network configuration involved? I was having the same issue with Xamarin.Android but didn't get as deep into it - I assume it is the same root cause. Thanks!
