My support case seems to have been abandoned. It used to be possible on previous machines. I can't access the online materials library anymore with MXED v3. Turned out to be the result of a spelling mistake in a file name and the license file being misplaced in the directory structure which can't have been user error because it was a completely fresh install. This was solved remotely after more than a week of emails back and forth. V3 refused to run freshly installed on my new MacBook. When I start a support case, I typically get a first reply pretty quickly but after that first reply it may hang indefinitely. In general I find Next Limit's support disappointing. I'm still on version 3, which works for now.

I agree it would be nice to have a special offer to upgrade to a combination of plug-in and Studio. I don't actually know whether this is true, since it is such a long time ago that I bought v3 with the plug-in and Studio together. I think from Next Limit's perspective, they say that the license is cheaper now that you can buy the plug-in license and Studio separately.
