I've been in your shoes, believe me! And I've noticed it's a common occurence but I put the facts (the slim facts) together and worked out a solution.

I'm on a Mac by the way...

Anyway, do a Google search and find a free download of Limewire
ver. 2.4.4...

I installed 2.6, then went back to 2.5... with NO SUCCESS whatsoever...

...NUTHIN, I tells ya... then I UNINSTALLED them and put 2.4.4 on and GUESS WHAT?

Yep, you guessed it... I'm on.
