Update version 1.1.4 - 9.October 2009:  From N1MM version 9.9.7 XML protocol was changed again - this means the gateway software had to be changed again ! You need to uninstall previous versions (do that via the Windows ControlPanel).
The complete package including VB6 source code can be downloaded here.
If you have installed the old version uninstall it through the windows control panel and reinstall it by running the *.msi file included in the zip package.
