If you are getting the "Client not responding" Violation, try reinstalling Soldat.
If that fails to work, do the following steps.
1. Uninstall Soldat.
2. Go to My Computer and type in %appdata% into the Address Bar and press Enter.
3. Find the Soldat folder there, and delete it.
4. Install Soldat 1.4.2 again.
See if that works.
Note that if you can't find an Address bar in Windows Explorer (the window that appears by going to My Computer), you can type in %appdata% into Internet Explorer and get the same result.
