cosworks.dll cannot be loaded

Ever since installing '09, I cannot load my Simulationadd-in. An error comes up that says "C:\.....\cosworks.dll cannotbe loaded. Either the Add-in or one of its components is missing"

The file in question exists in the location it says. The otherPremium options like Motion and Routing add-in just fine.Simulation is the only problem. My IT has tried everything my VARcan think of short of re-installing SW. This same problem alsocomes up when I try it on my coworkers computer. We are usingmultiple network licenses, one of which is Premium, the others areProfessional. When I load in Motion, my SW goes and grabs thePremium license off the network just fine. Adding Simulation atthis point doesn't work either.

Anyone seen this? Any ideas?SolidworksSimulation
