HI, am having problems ..system worked ok 2 days ago, ,but now no matter if I search for audio files by Genre, ARtist or title, the lime wire signia spins for about 30 seconds..but NO RESULTS are posted..just like it goes into lala land or something. Do I need to re-install the software?? is this a common problem..if so, please shed some light as it's quite frustrating.
