lisence

Hello: We are using illustra but we only have 5 license. We create two common counts for access the database, with these more users can access the database. The problem we have now is: Altough we use this common counts if the 5 license are uaed some of this with the common counts no more users can access the database neither with the same count. I really don't known why this happend someone knowns? I suppose is because illustra interpretate the process not the users is this correct? Thanks for your help Cristina
