activate your license in web account;
assign password for your platform in web account on "My computers" page - you will need to toggle "allow this platform to log in" option - and press Submit.

then specify your account name and platform password from previous step in ZModeler's "Account Setup" window; then restart ZModeler.

Note, you need to run ZModeler as Administrator for license installation and validation; the rest of time ZModeler can be run in a regular way.

I have followed the steps but when I open Zmodeler3, click on about, Click on license information, Hold shift for 1 sec... Nothing happens. Shows my Platform ID and then says "you can create an account at www.zmodeler3.com/account and register your platform ID there to get a trial license. To let ZModeler install license key, specify account name and platform password on the next page." Everything is correct but I still can not import anything. No license has showed up. Please help. I just bought a year license.
