I just purchased 5 licenses. The 3 installations went very well and there are no problems, but the 4. has 2 mayer problems: 1. It cannot update 2. After running for about 24 hours it has a memory leak, where the program use over 100 mb ram. When trying to update, Nod32 comes with the following error: "Virus signature database could not be updated Error creating tempoary file." I tried to reinstall the program with as few running processes as possible. I typed and retyped my registrationinformations and that does not seem to be the problem. What should I do?
