Gus,
Can you tell me what two patches you have, as the hosts file and the .dll can conflict.
Also can you tell me what version of IE your using and if you have gotten any microsoft updates lately.
Can you tell me what message you normally see in the upper left corner under the WinMX v and Online status is... "Patch Operational" or "Please Be Patient" .. ?
We are online although WinMX is experiencing a error for several folks and at this time we are not sure what is causing this.
