When starting autocad (2004DX) and then while starting autocad starting autocad again, so I have 2 sessions of autocad, i get a computer reboot without warning and the license is corrupted.This resulting in needing a new authirisationcode from autodesk. If there is already a session autocad running and I start a new session there are no problems. So when starting more sessions and the authorisationcheck is not completed the computer crashes and I need a new code and need to reconfigure autocad to the users preferences. I am running AutocadMechanical 2004DX on 14 pc's with standalone licenses All the pc's have the same problem. Who can help me Is there a solution for the crash problem. I use a P4 2.8 wih I Gb internal (HP D330) with WIN200
