Don't know how to update to 8.5 on my Melco

[Donuk]

I am probably being stupid....
On my Melco N/1A I have Minimstreamer installed.
In Minimwatch, under installed packages it shows that I have:

minimserver-0.8 update-114
*minimstreamer - 0.8.4.7
minim streamer-0.7.6

I ought to update this, right?
I have nothing in the available packages box.


When I look in Minimwatch log it tells me I should update to 8.5

Do I just have to do a straight installation on the Melco on a memory stick to 8.5, and it will automatically overwrite the old one.

Thanks, muddled of York
