You have to login with the Graphisoft ID at myarchicad right? Because with the Graphisoft site I can log in normally, but it does not work on the myarchicad site. After I enter my email and password, it throws me back to the start page. Does anyone know what's going on? Need my serial number urgently.
There is no log in on the Graphisoft site, so I don't know what you might be talking about there. But, yes, you must use your Graphisoft ID at myarchicad.com
If you are unable to log in, try a different browser and/or clear the cookies/cache for myarchicad.com - or you may have a firewall issue.
At worst, in an emergency, create a new Graphisoft ID in order to get your student serial.
