hello,
try installing your winmx in a folder (program folder or any other will be fine), right now i think you installed it straight onto the desctop meaning all the winmx config files get installed at that same location (desctop) so removing those config files makes winmx think it has never been installed again and it makes you redo all that
enque should be there and a full install should fix that problem too i believe
hope this helped a little .. goodluck and greetings, ...Joshua203
