Hi, I am running SolidWorks 2008 with COSMOS on a macbook pro using windows xp through bootcamp. Solidworks runs fine, but COSMOSWorks and COSMOSMotion will not initialize. COSMOSFloWorks seems to start fine. I get a "COSMOSWorks authorization failed message". I was able to setup the license.dat file that was emailed to me. I see all the modules are available in the authorized modules tab. In the status tab there is a green check mark next to authorization, sentinal driver detected, and sentinal driver running. There is a red x next to sentinel dongel detected. However my PC runs cosmos 2007 student with the red x next to sentinal dongle detected just fine. I noticed that COSMOS 2008 student is running the 2007 version of COSMOS License administrator. It also says that license version is 2007 instead of 2008.
