After you enter your basic info for your new account, such as your Name, Username, credit card info, etc., you should be taken to the Ace of Sales Setup Wizard to add your Brand Identity elements (your logo and company color) and Contact info. However, if you can’t get to the Setup Wizard you may need to update to the latest version of Flash (it’s free).
Just go to http://www.adobe.com and click the "Get Adobe Flash Player" button near the middle of the screen. Then follow their installation instructions (it's fast).
After installation, log out of Ace of Sales, log in again, then you should be able to complete the setup process.
