No you can't blame them, i've experienced the same frustration as them..connection problem's ,,fake files..ect, but i didn't give up, another great thing about winmx is it gives faster d/l speeds for 56k users then other p2p apps, i've tried other p2p app's an i got slower d/l speeds on them then i do on WinMX.It also has openNap protocol in it too ,so if you having problem finding a file that the cartels are flooding fake files of on the WPN you can always try to find them on OpenNap.
10 patches

I've only had to install one patch(KM's patch) with v3.53. that's only cos the cartels are attacking the WPN.
Of course they are losing now but they're gaining more legal right's to sue people & to sue p2p software companys.They're are frustrating people so much that they giving up on trying to download from WinMX or other p2p apps,when they use their dirty tricks to attack the p2p networks.Which is against the law i believe aint it?

But again they think they're above the law and can get the laws changed whenever they want to.
