I tried "evaluate cell" command from the menu, but it doesn't work either. > Does anyone know what could be wrong? The information you give is not enough to really understand what's wrong, so you will get some wild guesses about what could be the problem. Here is mine: for some reason you probably can get a license for the frontend but not for the kernel. I have seen this happen for network licenses and at least for version 5 the behavior was exactly as you describe. So if your license comes from a server, you might want to check that there are free kernel licenses available... hth, albert
