A couple of things, I assume you have tried.
1. after downloading xl prerelease, then overriding with xl2 goto setup menu and download tab and download list. Then download both the XL files. Then you will install. This will bring XL to the current release upon restart. If the download list are red dots then its not up to date.
2. When installing winamp, are you modifiying the install or anything? Is winamp installed in the common, C:/Program Files/Winamp or is it off somewhere else? Are you installing winamp agent?
I have never seen Xl not allow one to add a player/zone. When XL is working correctly, winamp should automatically start upon load of xl. The playlist will only ever show 2 tracks, although in XL it shows the whole playlist. If you are starting Winamp b4 XL or manually loading it XL will not communicate with it.
