When you got rid of the NAT firewalled error on Azureus, did you use UPnP or Portforwarding. Limewire should be exactly like Azureus to Portforward. The only difference being the listening port setup (In Azureus you only choose 1 port, in Limewire 2, but they should be the same port). Also if you use both at the same time, then you need to use a different port for Limewire, than you use for Azureus.

But it really sounds like the files you are having trouble with are just bogus files. A rule of thumb can be if you get more than 1000 results for a search, and you haven't used get more results on it, then most likely most (if not all) are spammed bogus results.

Lots of tips on how to avoid them here (does not just apply to music):

but shouldnt the brick wall go away when the firewall is off, completely off. and i tried downloading like 7 versions of the file i wanted, i tried ones with 100 peers, and others with 10. Ive got no clue whats going on with it.

ok, so i read the thing about fake files, and so i tried searching for just the title, and i got a download working, but the brick wall still concerns me, whats up with it being there if Limewire isnt restricted at all?

It wouldn't be there if Limewire wasn't restricted at all. The brickwall means that you are not recieving incoming.

Try backtracing your steps for portforwarding Limewire (I bet you'll find some small mistake).

I forgot to mention that you need to forward both TCP and UDP for the port. If you managed to portforward to Azureus, then I really don't understand why you're having trouble doing the exact same thing for Limewire.

am i supposted to be able to download while it has the wall, cause i can

You might be able to download from people, but other people can't download from you (you won't see many if any uploads).
