I have recently upgraded to SL2015 on three separate companies. Now I'm having a problem with users on one of the companies getting the 'You have reached the maximum number of users. We have not had an increase in the number of user after the upgrade.
The other two companies have a similar number of users and no problem is experienced.
I have tried to repeat the upgrade but to no avail. I have also tried to apply the registration keys again but there's no change.
Please help.
