My current website was created using CoffeeCup Visual Site Designer. I am trying out Responsive Site Designer. Your examples use Coffeegrinder DDE, but I can't figure out how to start with that Grid. Mine always starts up with Wave Weapons United and uses Foundation 6.3.0. I'd prefer something generic using Coffeegrinder DDE. Did I do something that changed the default?

Go to File then choose New from theme.
This will allow you to pick the frame work you want to use.

Not sure why, but nothing was there to open. I finally decided to try making one with Responsive Layout Maker Pro and that did it. I never had time to figure out Responsive Layout Maker Pro, so didn't even know it could make one for me. Not sure that I need both Responsive Layout Maker Pro and Responsive Site Designer. Site Designer is looking like the right one for me.

And thank you for responding quickly. That's why I like Coffeecup software.

After reading more of the forums, I learned Coffeegrinder DDE is old and bootstrap/foundation are the new ones. I guess I should get with the newer stuff!! Thanks again for your support. It's great to have help!!!
