today i installed the server and web-inferface (windows installer) in V4.4.0.

Server is running and functional, web interface is throwing error message:

14:47:40.874 [UIThread [6c74bd29]] ERROR org.netxms.nxmc.Startup - Login job failed
org.netxms.client.NXCException: Der Server benutzt eine nicht-kompatible Version des Kommunikationsprotokolls (server=[60, 4, 1, 1, 1, 45, 1, 2] client=[60, 4, 1, 1, 1, 44, 1, 2])

Seems the WebUI Installer needs an Update...
