Warrior Queen items won't allow double click, and autofit doesn't always work

I'm a new user and is trying to load Bodica Panties and dress on to figure. Normally when the cursor goes over a piece of clothing I should get "double click" to load item. All that comes us is a description. Next I have tried dragging item over to figure, normally in the past I get the message fit to "victoria" or which ever model but now I just get the small plus sign. This is very frusting as I am working on some Palace Guard amazons but none of the Warrior queen items seem to want to work. Please I would entertain suggestions, but I am not a Techie. Further I have asked they the designers put in more tutorial videos that would show us how to fix issues like shields merging into thighs etc. Can anyone give me some simple help - remeber I am not brilliant - I little better than a raw newbie. Any help would be most appreciated. Cheers:)

Is this the Warrior Queen you are talking about? http://www.daz3d.com/warrior-queens
If yes, the outfit this texture is made for http://www.daz3d.com/she-war is for Victoria 3. That is NOT a Genesis 3 figure, but a very old figure. Which figure are you trying to fit the clothing to?
And also note that that Warrior Queens is a texture set, not models, so what you are seeing is correct - the + indicating that the materials can be added to the model under the cursor (if it matches) and double-clicking reading the materials in and finding they don't match the selected item.
