When I try to launch the PolySpace viewer, I get the following error:
ERROR: Message
License Expired on (expiration date)
Current Date is (today's date)
After clicking OK, I get a second window that has the following message:
ERROR: Launching the main class

This message indicates that your PolySpace license has expired. If you are licensed to use R2007a or higher, you should upgrade to this version. Otherwise, you will need to contact technical support and have them generate a new license file for you.
To contact the Installation and Licensing team you can submit a request here:
