Thanks for the suggestions, Heyward.
Unfortunately, it still isn't working. I don't think it is a permissions issue because other files in the same content folder do work. It also is not an individual PC issue because it does the same thing on two different PCs and in two different meeting rooms with different content libraries. .
I have asked the instructors to just upload their documents again, but they are not too happy about that. So I will contact Support.
Thanks once again.
So, as I understand it you are trying to load powerpoint presentations previously uploaded or loaded into the content library when you were on Connect 7.5. Now you try to load those same files into Connect from the Content library?
Understand, that of those files or ANY files that contain AS2 then those files will corrupt the room youa re using until you reload the room.
It is recommended that you download those files from the content library onto your local disk, then open them up with Presenter or Captivate and save them (if they were Presenter or Captivate before). If not, then re-upload them from your local disk. This will cause them to be converted.
Loading AS2 content in Connect 8 will sometimes load but at that point they have corrupted the Flash instance and you will see strnage behaviours like this.
You need to re-load all your old presentations this way to make sure they are converted to AS3 based powerpoint/flash files.
