What do you see in the Help > ARM License Manager... dialog? In particular is there a warning icon and/or information in the tooltip for the license file? Is there a toolkit selected in the popup menu at the bottom?You can also look in /home/tbase/.ds-5/licenses/DS-5 Professional (30-day Evaluation).lic check the date on the 'INCREMENT compiler5' section. Or perhaps just attach the whole file to this thread.
