Mvision HD200

I've got my old Mvision out of storage. The idea is to set it up as a freesat receiver for my son. I saved the old channel list to my USB stick but after updating it with Setedit channel editor, it wont upload it. I've reformated it and I've tried different memory sticks, but all the box does is reboot itself.
I'm thinking of doing a factory reset, but if that fails to sort the problem I might not be able to reinstall the firmware.
The last time I used the box it was ok. (3-4 years ago)
Anybody still useing this box with any ideas?
