Hi wigganner
If your not using opennap and still having this problem:
What happens is this, you change over to 3.54 which has a slightly different arrangement on sharing your files and folder. If you share say a folder called My Music, then inside you had a folder named My MP3s. You shared the My Music folder then it asks you when you do this 'Would you like to share Sub Folders' .. if you allowed it (its allowed by default) then went and individually shared the My MP3 folder also WinMX 3.54 sees it as two different files. Some folks do this on purpose thinking it will increase the speeds its uploaded at, there are better ways to do that.
My best advice is to visit here:
https://www.winmxworld.com/tutorials/sharing_on_354.htmlRead through that, then unshare and re share your files so that its only sharing one copy of it.
Let me know if you still have problems
