WebEx Error

I have been struggling to get WebEx to work now that I have upgraded to Ubuntu 9.04.  I get the error below, and it failes to continue loading.  If anyone has any ideas, please let me know.  I did just upgrade to Firefox 3.5, but that didn’t fix the problem.  I also did a search on Google, and that didn’t turn up anything.

I did check to make sure I had the ubuntu-restricted-extras and the libstdc++5 installed from this earlier post.
