Hello serenity, it sounds like your using some other variation of winmx and not the original winmx. WinmX is free and always has been.
You can download the original winmx >>HERE<<
The original winmx is currently under attack due to a couple of former disgruntled users. Searches will display results that have nothing to do with what you searched for, and chat room listings are also affected. A fix for these two issues is in the works and will hopefully be completed soon.
Be careful of the winmx you used previously as there are quite a few bogus winmx editions floating around that contain spyware and other nasty stuff.
