Thanks for both replies. Still no luck though.

I'm all clear on and fine with the two-step login process (log in to the library website first, than log in to Zinio). The problem is step 2 isn't working.

A neighbor told me today he's been having login problems with Hoopla too.

Someone commented to me that if the problem occurred across all apps and operating systems, it wasn't really the service provider's server but rather its database that was the problem, i.e., the database not acknowledging my login.

I emailed the local librarian; she emailed back to say what the correct user name was for my account, I replied that that was indeed the username I was trying to log in with. Haven't heard back yet. I place some hope in the local library as its patrons' advocate in trying to resolve such problems.

I got an email back from Zinio saying basically that they don't provide support for Zinio for Libraries and giving me an email address for support via RBDigital. I'll see and report if anything comes of that.
