SWF plays in preview but not when published

I have seen similar issues posted but none dealing with this precise problem. I

have two SWFs, one of which loads at the end of the other. When SWF 1 is played

back in Flash or when published in HTML format, SWF2 plays as is should. When 
SWF is exported to another program (e.g. Frontpage or Ektron, CMS), SWF2 will 
not play. Interestingly, when SWF2 is exported to the other program on its own,

it plays fine so font support is not an issue.

 I have also tried altering the level in the LoadMovieNum script (0, 1, 2) as 
well as republishing both SWFs from the original FLA file. So far zippo.

 Any ideas??
