unable to log in.

I cannot log in. and gives a link to the site, but the password and login are the same. from the site I can log in, but not in the programme, reinstalled many times, nothing helps, and changed the password, someone tell me what to do?

Please use English !

The problem that you describe usually is on Mac computers where people confuse the N.A. log-in with the Mac security pop-up, but from what I can see then you are on Windows.

You can try first uninstall both Native Access and the NTKDaemon

then run the NI reg tool and remove anything Native Access and NTKDaemon ,

then use Windows Explorer to search your system drive for all instances of 'Native Access' and 'NTKDaemon' and delete it all .

Then restart computer ,

then download latest version of Native Access for your OS

then reinstall Native Access as an Administrator .

And where can I download Native Access - 3.17, on the official site only 2

What you download from above link ( latest version of Native Access for your OS ) is the latest version of Native Access (at present version 3.18.1). The download says N.A. 2 but that's just a name used since the name has not changed since it was really N.A. 2 , now the N.A. 2 is just a name and version number is 3.x.x. Yes , that is confusing , but that is how it is.
