You'll likely find more information and assitance n the Centrafuse forums here: http://forums.fluxmedia.net/
If you're not seeing artist or albums, you may need to re-import your library, or it may be that SQLCE 3.5 didn't get installed properly and you'll need to do that manually.
The weather issue is a problem from Weather.com. If you put in Sydney, you get the values in centigrade, but put in Cairn, and you get it in farenheit. I have no idea why that is, but the app just reads the data it's given. There is no conversion going on.
Again, all these questions are probably better asked over onthe other forum.
