I visited a customer office to install Accuterm on their workstations.  On 4 of the 5 workstations I was able to authorize the AccuTerm using an "Administrative User and Password" issued by their IT department.  On the last workstation I ran as administrator, I entered the user and password when prompted, but when I entered the authorization screen the "Authorize AccuTerm" icon was dimmed and I was unable to complete the authorization.  They purchased a 10 user version.  Does this mean that the administrative user issued by IT was not valid for that workstation?  All the actions leading up to that appeared to be normal and identical to the other 4 workstations.
