I installed R14 but it still didn't work. I don't have a C: drive on my computer and I'm working off my F: drive. Does this matter. I go through the steps to load up the file through the command "menuload" but gives me a messsage about not over writing menus or someting and asked me to continue. After continuing I do get a menu called "TCAD" with a pull down call"Timbercad", under this is things like Rafter, Purlins, ect. But when I click on any of these, in the command line it says it dosen't exist. I'm very confused and frustrated, can anybody help. My operating system is XP
