Downloading.
 

Whenever I try to download a song under a different Windows XP account, it refuses to DL. Double clicking it/right clicking and clicking download does absolutely nothing, nothing shows up in the transfer window, etc. etc.

Norton is disabled, Windows Firewall is not up, and still nothing works. =\

Check and see if you have the lisence warning ticked...
Go to Tools > options > Searcing > Lisence Warning and make sure the box is not ticked and select apply...
