FYI we have version 5.
You would need to have at least version 7 before the latest release of server could host your files. The change from 6 to 7 marked a change in file format that prevents older versions from being hosted by FMS 10.
It is possible to convert your 5 files into 10. You can download a trial copy of 10 to investigate whether this is easy or hard to accomplish.
thanks for the quick reply, friend.
