Have you checked your license file.. is there an expiry date? Normally, on the anniversary of you having your software you will receive an updated license file. If this doesn't help then I suggest you open a ticket on SupportNet.
I believe you mentioned in a previous post that you also have VeSys Classic on that machine or one of your machines? It would be interesting to check to see if VeSys Classic Components can run, if not then it is likley that the machine you are working on cannot see the license server. You could also try pinging the license server.
Found the problem. When we installed Vesys Classic the license was installed on a server like it should. When we installed 2.0 we built a dedicated server for it and put our renewed license on it. The client machines never got the enviroment varialbe changed to look at the new server, so when the license expired on the older server we went done. All is good now.
