Flash Website won't load for some but works for others...please help!

I’ve created a flash website that loads perfectly for some, but others report they can only see the start of the flash movie and it just seems to stop/doesn’t load (seems to be IE users). Safari, Netscape and Firefox loads it with no problems.

I can view it fine in IE6. I just can’t narrow it down to whether the SWF file has been embedded incorrectly, or if it’s a caching problem, or a browser problem?

code is:

<object classid=“clsid:D27CDB6E-AE6D-11cf-96B8-444553540000” codebase=“http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=5,0,0,0” width=“700” height=“570”>
<param name=movie value="/tophoto_final_06.swf">
<param name=quality value=high>
<embed src="/tophoto_final_06.swf" quality=high pluginspage=“http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash” type=“application/x-shockwave-flash” width=“700” height=“570”>
</embed> </object>

Anyone’s help would be GREATLY appreciated!! Thank you!!
