FO CLient experience

Any one using FOClient on W2K?
all the time I get a error in MS O2k that a dct could not be read nor written, when I want to save my DCT as DCR.
Well actually, I can't use any save process through TeamSite.
But I have full permissions on the file system, and when I save the file directly in word as doc file in the specific workarea /template/ ... data dir, then there is no error.
