Error in Harmony

I have a Imac and a MacBookPro. I activated Stage Module in the Imac as server and later in the MacBookPros as client. The problem was in Stage when selected the option “work in database” the program closed with error, just worked it the option “offline”. Is the same in the client machine. I tried open the others modules (paint, play, scan, xsheet) from the finder and the modules closed with error. I tried creating a datebase in my server with Configuration Assistant in the tools, but now I can’t open the Stage Module. Appear this: Unable to find a valid license for this application. The license activation wizard will be launched automatically…

If you have the Standalone license for Harmony, then you can’t run it in a Server configuration, you can only use Stage and only in Offline.
