I'll see if I can get an opinion on this. But looks like a specific computer case.

You could go back to LW 4.18; just choose Old versions link from the download page. But you would need to remove the install limewire.pkg file from receipts folder if you did, otherwise the older version would not install; Receipts folder sample image

BTW did you try setting up an alternate account to test LW out?

well, i didnt set up a different account, but i tried it on my other mac and it worked, so i guess its my comp.
