The "content file locked" message indicates that another program - most likely an antivirus program - prevents Steam from accessing the game files (so Steam is unable to update the game). Especially "Avast" causes such issues lately, but other programs like AVG can also be responsible for this issue. What antivirus program do you use exactly? Make sure to put Rising World on the exception list of your antivirus program, or alternatively disable it temporarily until Steam has updated all game files.
About the server issue: Make sure you've forwarded all ports in your router, by default it is port 4255, 4256, 4257 and 4258 TCP and UDP, as well as the http port 4254 (the error message indicates that the hive server was unable to query your server, which is usually caused by a blocked http port). You can visit this page to check out if the ports are forwarded properly: http://www.yougetsignal.com/tools/open-ports/
If it still does not work, please let me know ![]()
