Mate, I tried with my home Laptop but had 2000 pro on - had an old copy of 98 but found my son had used it and scratched the CD so its useless....!! I did however manage to optain a copy of Nortel PCMCIA Programmer V9 - AND, GUESS WHAT.....it didnt work! Oh deepest joy. Im giving up with the backup for now and just going ahead with the import of a new music file - hopefully this wont affect the existing MOH and instead create a separate file so I can apply accordingly - if its no good then Im hoping I can simply find the original MOH and re-apply...?
