Hi Nick - we're sorry you haven't been contacted yet. Let me jump on this today and I will get the relevant person back to you.
No worries. I just wanted to make sure that was the proper path. I had talked to my reseller and he wasn't entirely clear either. Figured maybe I was doing something wrong to not get the download option.
