okay, so i have this same problem with my installation of MT, once i switched over to version 2...
i did read the instructions on installing file::spec
here...
forgive me for sounding dumb, but after reading this i'm still not quite sure how i'd install this. i don't host the site myself; does that mean i'm going to have to talk to my web host about installing this on their server? or is this something i can do myself? any help would be greatly appreciated, thanks.
