Lost Engage Interaction During Upgrade

Hello,

I have a course built in Presenter 09 that contained an Engage interaction.  I need to remove some content from the course and when I make any form of edit I receive the message saying the project must be upgraded to the new version (360).  However, when I upgrade it I lose the existing Engage interaction - the slide turns static.  

I read that I simply need to insert the Engage "intr" file - but I do not seem to have that.  I do, however have the "swf" file and it plays perfectly outside, but when I insert it into my course it does not play.

Any help would be much appreciated since the Engage interaction contains quite a bit of data and I would prefer to not have to recreate it.

Thanks in advance!
