Automated borrowing of license doesn´t work

[3d-laboratory]

According to the help it is enough to connect the workstation to the internet short before the borrowing period of 14 days is over. So I made an outlook appointment every 13 days and connect the internet while working with Vray. Sadly this doesnt´t work. Every time I have to go through the borrowing process. Ok, it lasts two minutes, but it stops the workflow for a while. What do I wrong? When exactly I have to establish a internet connection or what do I have to do? Do I have to start MAX during the connection? The version of my license server is 5.5.3, the newest one.
