This is straight from the SignCut web site "SignCut-X2 is available in two versions. The SignCut-X2 PE which is the fullversion and works either by subscription (which requires internetaccess on the computer) or by purchasing a dongle.
The SignCut-X2 LE version is a slightly restricted version and does not require internet access."
I have the SignCut-X2 PE (full version) and do not go through internet access, you purchase and register through the internet, thats it, you do not need the internet on to operate it, or do I have a dongle.
