I have Downloaded DMX Zone960 Grid System (free extension) and it was installed properly is it enabled, but i can't see the toolbar for the extension, I'm using Dreamweaver CS5 Version 11 build 4964 English version on Win 7 Ultimate in Spanish, i hope someone could help me.
the extension is located in the insert panel, default in CS5 this is not displayed as a tab like on the screenshot with the extension, it is in the dropdown menu. you can change the look of the insert panel to look like the old tab toolbar in older Dreamweavers
default the the insert panel is on the top right side, you can change it by dragging it to the top or change the view from Dreamweaver to classic, then you will have the panel as a toolbar at the top.
if still having problems then post in the support forum at the product page or contact the live support.
Guys, PROBLEM SOLVED HERE, Im using Windows 7 (64bit) and Dreamweaver CS5.
Just click on HELP then EXTENSION MANAGER. A window will pop up. Make sure the box bellow the ACTIVATE title is checked. (of course it has to be in the same line of the DMX Grid plugin). That's all! Simple and direct!
