Problems with release 11.5.5.553?

I’ve been having a number of issue with Captivate over the last month or so and I’m trying to figure out if it’s just me or if there is/are a known problem/problems that might save me from having to throw about 6-weeks worth of work in the trash.

I’m working on a scenario based course that takes the learner through an activity and asks policy questions at various points.  If the learner answers incorrectly, they are routed to a remediation slide where they are expected to use the reference document to find the right answer.   When they find the answer, they put the paragraph number into a text-entry-box and a shared action checks the answer and provides the appropriate feedback.

The current problem is that the while this functionality all worked 2-weeks ago, now that I’ve updated to 11.5.5.553 it doesn’t work anymore.  For example…the correct answer is 7.5.A, but if I put 6 into the TEB and run the action nothing happens.  Put in 7.5A and it gives feedback that the answer is wrong, but put 4 back in and again nothing.
