Much antivirus softwares deleting important files without warning, then the NCK products do not work properly.
As an example here Panda IS 2013, but that's the way it works in many other software products, see this:


Suggested solutions:

Use AVAST antivir, great work with the GSM softwares, do not delete important files.
All NCK products install one folder (example: C:/NCK) and add complete folder in antivirus software white list, exceptions list, etc.
If you have deleted important files, NCK reinstallation required.

I hope this could help you.
