I found this from someone in the ProConnect Facebook group about people asking the same thing

"Is this a return that you had not yet burned a credit on? Seems thats the issue with everyone....if it's a return you had already purchased then you can print....but if it's a return that you had not yet purchased or used a credit on then somehow that's gotten tied into this Jan 13 date that restricts printing at this point."

So I'm guessing that is what is happening with yours as well. I think its all tied to the renewals that are processing. I just saw mine process on my credit card. So hopefully soon this will all be fixed.
