I downloaded and installed Circuit Design Suite 14.1 today to evaluate Multisim for a project that I'm working on. It installed fine and was up and running on a seven day eval license but a there was an option to extend the evaluation. I opted for the extension, a few updates and installations ran but now the license manager indicates that the eval has expired. I haven't used the program once. Ultiboard seems to be licensed but not Multisim.
I recommend you go to this link and get a free serial number. It will work for 6 months, with the Student Version. It says LabVIEW but it works with Multisim too.
