i have basic LW as i am just trying it at the moment and if i like it i will sign up for the PRO.

I have tried to download some songs and i come up with a message saying need more sources. What doesn this mean?

and also what do the other types of speed mean and can i also download these files?
I have DSL so i was wondering what do T1, T2 and higher mean?

could the reason that i cant download those files is because i have basic LW? how much is it in British Pounds to buy LW PRO?

Thank you in advance.

also can someone tell me what all those different files mean?
wma,wmv, avi, ram, mpg (i know mp3!!)

thanx
