Cosmos installation

Hi to all,

I have installed the Solidwork 2008 Premium on XP Pro Windows pc.Everything is ok apart that I can not run Cosmos. Actually I boughtsolidwork to use cosmos !!

When I try to activate from the option menu I get the message that"cosworks.dll" can not loaded and/or plugin missing.

How I can solve the problem ??
