friendlyway composer network services

1.  I have installed composer network services on own server. While trying to register a terminal through the webconsole, I'm getting the following error: "System.Runtime.InteropServices.COMException (0x800403F2)…". What can cause this problem?
2.  The status of a terminal indicates Failed. If I go to this terminal and open client service control center, to check the settings, I cannot upload the configuration to the server. The following error message is being displayed: Terminal profile cannot be loaded. What can be the cause of this failure and how to solve this problem?
3.  I installed CMS Extension pack and successfully uploaded my contents to the server via Network Services in composer 7. But when I am trying to upload the project in Internet Explorer via WebConsole I am getting the following error message: CMS service is not installed. Please download and install it now. How can I solve this problem?
4.  I can't log in to my account on your composer network services server www.composernetworkservices.com (or www.clientmanager.net in case of using the old server) since the Login button is inactive. How can I log in?
5.  I am getting the following error after logon to the administrative console of composer network services: ErrorSystem.Web.HttpException: Exception of type 'System.Web.HttpException' was thrown. ---> System.Web.HttpUnhandledException....
6.  I am getting the following error after logon to the administrative console of composer network services: Failed to access IIS metabase. The process account used to run ASP.NET must have read access to the IIS metabase (e.g. IIS://servername/W3SVC).
7.  I can establish a VNC connection to my terminals by using the remote service button in the webconsole, but the VNC area remains black. This problem occurs only on machines running under Vista. Is it possible to solve this problem?
