I got limewire 4.12.3 a couple of days ago, and it was working fine until yesterday. I can download song files, and anything else, just fine, but whenever I try to download a film file of any media (mpg, avi, etc.) I can't. Even if can se that it's available in the search, I'm told that the file couldn't be downloaded, or that there weren't enough sources.

What can have caused this problem, as it just suddenly appeared? I haven't upgraded my firewall (which I've set so that it doesn't cover LimeWire), or done anything else to my computer. Please help!
