Hi, just a thought, when we have problems with the schedules overwriting the original we have found using the clear facility (the bin icon on the toolbar) before resending the new schedule data often works.
if not try remoting to the client (using a full version of vnc external to the server software so you can take full control of the client screen) then manually delete all the old files related to the schedule.
if it helps let me know as it seems to be a problem for a few people on here.
After I cleaned the used the bin icon on the schedule it does seems to work again.
I'm going to keep an eye out if anything changes.
