Can you post a screenshot of the error?

Thar be snow. Oh, wait. I mean

You shouldn't... If you mean you have more than one folder called "materials" and "scripts" it isn't possible. Make sure that it's not "materials(1)" or "scripts(1)" or "script" or "material" etc. Make sure it's exactly like that and then it'll ask if you want to merge the folders, just click yes. Alternatively, you might be talking about something completely different and I'm wasting my time :D

Well ur right i tried the materials(1) but that still dosn't answer my question. it wont lemme merge. like lets see it says replace only. it says replace materials with materials "yes" "yes all" "no" "cancle"

Really confused how do i merge it? or can i just put that the skin materials in the material files then would it work? u hav to show me how to merge 2 folders

Srry to tell u im running XP
