Unable to install with Melco N1

[pdcman]

Hi all, first post.

I am trying to install minim-server for the first time to my Melco N1.
I am getting as far as putting the usb stick in the backup port, selecting backup and restore etc, but have the following message:- 'cannot restore from newer version'. Any ideas what I need to do next?
Thanks
Phil

update: I needed to update the melco software to 3.9 first. I have got as far as step 10 successfully. However, the front screen is now displaying normally, it doesn't appear that it is installing minim server. (the usb stick has been moved to the expansion slot as instructed) Is this done silently in the background?
