How do I upgrade , Please?

[davewnaim]

Naim installed Asset on my NAS many years ago and its been fine untill recently but am now experiencing problems. Checked and its Version 6.2 so Im sure its in need of upgrading. Also its Premium. At the time I didnt keep very good notes of what was installed (just wanted to get my streamer working). How do I do the upgrade please. please? Installed on my QNAP NAS.

thanks
dave
