I am running SolidWorks Premium 2010 SP2. I also have a seat of NEI Fusion 2.0 which consists of its own solidworks install with an NEI Nastran plugin. Prior to upgrading SW Premium from SP1 to SP2, the Nastran addin appeared in the addins list and could be selected and started. After upgrading to SP2, the NASTRAN plugin does not show up. Any ideas?
