Not a valid logon token Error

Hi,

I am linking multiple swf in a main swf. But i am getting not a valid token error while moving between child swf files.

The URL for accessing swf file is

"http://<Server_Name>:8080/ businessobjects/enterprise115/deskto

plaunch/opendoc/documentDownload?iDo

cID=10348&sKind=Flash&CELogonToken="+ <Linked to a Excel Cell>

Please help me to solve this problem.

Regards,

Sathish
