I am guessing you are on Vista/7+?
Re-install DBPro in a folder not in Program Files... so maybe C:\DBPro for example...
This will remove so many issues you will come across...
You can also try for the time being running the editor in Admin mode right click the shortcut or exe and select Run as Administrator...
Did you buy DBPro or the Bonanza Pack?
Stating your system information, such as Operating System, Install Location, Ram, GPU, CPU etc. helps when asking some types of questions, removes the need for someone to ask you for that data
Also Welcome to the Forums...

Enjoy your stay
