Cannot edit slides with SlideDeck 5; reactivating previous version.

I’ve been getting a recurring message in my organization’s WordPress site that my SlideDeck 3 license is expired. When I clicked on the link to renew my license, I was taken to a page that wanted to add me to some email list. I registered my email and received a link to SlideDeck5 and an Add-On Access Key.

I deactivated the previous version of SlideDeck 3 that I had on my site and then installed and activated the latest version of the SlideDeck (5) Plugin. All my SlideDecks appeared as hoped for, BUT the slides with HTML content showed up black. I went to edit those slides to see if I could fix the issue and found that I could not edit the details on any of my slides. Is anyone else running into this issue and is there a workaround that you’re using? If no workaround exists, does the Plugin Author know when a new version of the Plugin will be released?
