I've been having the same problem! I just installed Limewire 2 days ago. For the 1st day and a half it was unbelievable! I was getting several "hits" per search and had no trouble downloading. Now, none of my searches work at all. I'm still connected to the internet, and I can see that I am still able to download with respect to files that had already begun but now are queued. Any thoughts anyone?
