i use an i-mac and ive tried and tried and tried with the free version, but i can never completely download anything. the speeds are awful. i have a dsl modem and i download at .04 kb/sec from a T3. on larger files (especially videos) the downloading goes backwards! i would start downloading and check the progress every now and then. once it would reach about 20%, it would start from the begining, but the progress bar still read 20% complete! i was fed up needless to say, so i bought limewire pro. guess what? its no different from the free version! just as slow, same downloading problems, frequently disconnects, and i still cant play mp3's! i would like to know if anyone else has this problem and knows how to remedy it, or i would like my 10 bucks back!
