Checking out a license

We are on a SNL and I can check out any license just fine. Itsays I have the license and everything looks good until I try touse SolidWorks.

The license administrator says I have Premium checkout but when Itry to run SW it says invaild license server or somethign likethat. So I checked out both standard and premium and SW will load,but when I try to addin routing or something I get the samemessage.

Any ideas..????SolidworksAdministration
