CAN ANYONE HELP?

Good afternoon to all:When I try to use MSFS2K "download REAL WEATHER" feature, I can no longer make the connection to start the download. My hunch is that the file(s) that allows this to work has been corrupted or deleted by accident.I'm sure that a complete reinstall from the CD-ROM would get this working again, but I want to AVOID doing this so as not to lose all of the add-ons, modifications, etc., that I've made to the original program over the past year and a half.Does anyone know the SPECIFIC FILE(s) NAME(s) that would restore the "real weather" function -and- INTO WHICH FOLDER(s)THE FILE(s)should be pasted on my hard drive? I hope someone has the answer so that I can retrieve the files from the CD.I'd be very grateful...thanks in advance,Mike (DMD)
