Graal Crashing

[Crow]

Graal is sometimes crashing when I am playing an mp3 from my webspace...so there are a few questions...
1. Do you know this problem and maybe how to fix it?
2. Can I somehow force the client to download the mp3 to the Graal folder and check if its already downloaded?
3. Little bit off topic, but who cares...how do I change the downloading folder?(So it will download all the files to a single folder for our server.)

Would be cool if someone could help me out, its kinda annoying ;]
