I'd have suggested LW 4.16 instead. But your choice. http://www.gnutellaforums.com/mac-os...ck-lw-4-a.html & see the LW 4.16 link.

LW Pro do give support if you are still a valid customer: Pro Support

Else, try the beta LimeWire 5.2.2 (Beta) - Lime Wire
If you are a pro user, you can find the link to LW Beta Pro on right side of your Pro download page as shown here http://www.gnutellaforums.com/345055-post6.html

I must admit, I had same problem with LW 5 not running. I did as I suggested & LW 5.2.2 runs fine.

The beta of 5 did not work for me - and 4.18 seems to work fine. I will stick with that until LW fixes the problem. And thanks for the support link - i actually did find it eventually on my own. The response was to send me to their download page to get the current version again and re-install. It was I believe an automated response to my problem category - rather useless advice. Hopefuly we will get a quick response from LW - there are a lot of people affected here and on other threads I see. The beta works for some, not others.
