I have installed this, and when I opened first time, I had the Wi-Fi on. It downloaded 850 MB, than I downloaded the map for Romania, which I need.

After that I closed the program, disable the wifi, and started again the program for offline use.

But it says I can use only 30 days without internet.
Is it true?

What does patched mean?
It will expire after 30 days?

Please respond.
Thank you...
