Since the most recent update, any previously made captivate files we republish won't display

Question

(skip to "I'll break down the problem as best as i can" to avoid rant )
Essentially, we have near a hundred eLearning courses we have made using captivate dating back as early as captivate 4.  We have been upgrading through the versions as we go and where there has always been little glitches that present themselves this one makes the list sense.  This isn't even an upgrade in version, just a little patch (that seemed to add the ability to resize the "Question X of Y" bits on question slides).
So, does anyone have any help on this problem?  Adobe have been so far not very helpful, essentially offering the wisdom and clarity that comes with years of not trying to fix problems. Their advice being to basically remake each course from the ground up, something that will take a LOT of time (and for what!? to fix their mistake?).
I'll break down the problem as best as i can:
Since recent patch to captivate, pre-existing files that we publish again will not display on windows computers but does display on Ipad's, etc.  Uploading to a server does not fix the problem, it remains the same.  The internet window opens up the same as normal but after a brief loading bar moment, the window remains blank.  A check of the code shows that the files are being loaded but simply not displaying in any form.  If we publish a completely new file, it displays fine. The type of browser has no impact on the problem.  We have also found that if we go into the console and use a command to skip to, say, the second frame, it works!?  So the issue literally seems to be with displaying in the first place.
Thanks in advance if anyone can even help suggest ways to get round this problem, it has come at a terrible time when we need to make changes and present material to another company but can't even view our publishes files.

Answer 1

The most recent update (to Captivate 7.0.1.237) changed the default autoplay setting for all of our courses to on. Since we haven't changed any settings personally it was easy overlooked, and the autoplay function just doesn't seem to work.
I tried running cpCmndGotoSlide = 2 in the web developer console and it caused the course to start up, making me realise that the course was indeed loading (I saw that some of the content was loading on firebug but was unsure as to if it was the crucial files) but just not playing and I noticed while investigating that.
So its just a case of turning off autoplay for the course in the publish settings.
Also as a note our courses were still working on iPad, I think this is due to apple products not supporting the autoplay of content, especially if it has audio.
