I received the CD that you sent me. However when I try to zoom in on the electrical schematics I get a message: "click here to load plugin", when I do this I get the message:"suitable plugin not found". Do you have any idea what plugin they need. I have loads and loads of plugins in my computer as I do a variety of programs, ie., AutoCad, Adobe Photoshope, etc., among others. I also use Netscape predominantly. However, I have Microsoft Internet Explorer and Firefox as well. I don't see how this would make a difference.Sold!
