STAAD Advanced Analysis Plus Engine

It appears that we have two separate licenses of this, and STAAD is not using the second license when required. We were told by our sales person that this would allow us to run two STAAD.PRO with the Advanced license. 

The only option from STAAD is Advanced Analysis Plus Engine, when a second user tries to use the Advanced feature it logs an overage.
