Do you happen to know the link to that thread (so I can add a redirect from there to this thread)?

Does it freeze if you simplify the que--using just say an instruction item, the online item, followed by a simple image item (for example), and then a final instruction item? This is a quick way to troubleshoot, because it tests the functions while ruling out many other potential explanations. If it still freezes using an example like this, please post that simple version of the que and I'll take a look at it and see if I can tell what's up with it.
