I am a new WPMUDEV subscriber - and yesterday I got the Tutorial Video plugin; and I installed it. But, when I go to the tutorials 'it says my access is denied.
In my Network Admin WPMU DEV Video Settings 'it wants me to register the domain. Here's a screenshot..
I think the problem I'm having is that I am not using the subdomain method; but am using the subdirectory method for my WPMU network. Since the register info (pictured above) does not seem to handle directory paths in its input fields, I suspect this might be the problem.
When I checked your site for my registered domains however, http://dev.mendocinotim.com - the root domain for my network - is registered with you. See this screenshot...
