The problem is with the "/" character while saving the composition as shown 2nd screenshot you attached.
Thanks, that was the solution.
There's now a new problem, though. I upgraded today to the newest versions of Muse and Edge. The Edge composition is embedded in a Muse site as a scrolling animation. But if I output the composition after updating the file in the latest version of Edge, and relink to the new .oam file in Muse, and upload the site, the animation plays by itself instead of animating by scrolling, as it should. I think this is a bug. Can anyone from Adobe confirm this? (By the way, I relinked back to the old .oam file and that corrected the problem. But I need to be able to output the new .oam file and relink to that because there is a problem with the descenders in the text being cut off in the old .oam file. See http://NYCJazz.com, the title "Chuck Braman Jazz Groups," which is the display of the .oam file in question.)
Let me check this issue with product team and get back to you.
