If you did not Unblock the atb.zip file before you extracted it ,you may experience buttons on various pages not working as they should as a result of file blocking.

This is a security protection condition with Windows XP sp2 and Vista operating systems when you download files from the internet.

You have two options at this point.
First, and best one, is to delete the atb folder (not the atb.zip), Unblock the atb.zip folder and extract again.

Your second option is to unblock each file individually by following the instructions below.

If you click a button like Test View Page, Build Page Code or a Return To button in any of the screens and nothing happens or you see error on page, this is most likely a File Blocked problem.

Do the following:

On your Desktop Double Left click the My Computer icon, then select your
C:\ hard drive, then Double Left click the atbuild folder, then Double Left click atb folder. You will see the following screen.

Mouse over the file that is not working, for example, atbuilder.htm (Red Rectangle) file and right click to open the following screen.

Slide your mouse down to Properties (blue bar above) and left click once to open the following screen.

Notice the last item in the window, Security. See the Unblock button shown above, you need to left click the Unblock button, then the Apply button, then the OK button and the Property screen will close. Now do the same for any file that has the Unblock button showing in the Properties box.

You are done.
