I just installed DigMeta in DNN5.2 and it didn't appear to have any errors during installation.
I have submitted a support request, but I thought I'd seek broader help while I'm waiting.
It turns out that DigMeta (or something related to it's installation) was not allowing anyone to log into the portal anymore, causing an error after submitting the username and password. LUCKILY I had another browser open that was still logged in, so I removed DigMeta and all seems well again. That was a close one.
However....I do still really want to use Digmeta and the rest of the Dig modules I just purchased.
I'm suspecting there may be an issue with DNN 5.2? As I said, the install went well, but I couldn't see anyplace to get a code for activation, and I would also get an error trying to set up a connection in Digmeta (immediately upon selecting the type of module), so perhaps something didn't connect right behind the scenes. I have only just upgraded to 5.2, so I'm still getting used to the differences.
Thanks to anyone who can help figure this out.
