Hello, I was given a copy of SolidWorks 2008 EDU from my school and it has been working fine for quite a while. However, I now receive an error message when starting the program

could not obtain a license for solidworks. Server node is down or not responding
[-96, 491, 0]

Then it crashes. I've tried reinstalling it as well as trying to open it with my firewall turned off, to no avail. Does anyone know a solution to this problem?

Thank you in advance,

Alex
