1. I am using the student version of archicad.
2. Gray box does come up, as it was not verified yet for 1 year, but I have days of usage remaining, so I click "Start now" and it freezes.
3. My laptop is Asus G73SW-TZ060V.
(4.) After 3 days of trying, strugling to figure out the problem, going through all of it again, almalst giving up... I finaly made it. I checked if I had java and Quick Time 2-3 times before, but I tried to open Quick Time and i recieved some kind of an error. So I launched Apple update program and updated Quick Time to latest version and ran it to make sure it's working. Also I updated java as much as I could.
And when I did that, the program didn't respond at first again, but in about 20 secs it finally started.
I can't believe taht i threw away 3 afternoons of my time, but I guess it was worth it as now I can continue my work on the new computer.
Anyhow thank you very much
