In case you're still interested in xLabel, ...!
1. Check http://www.ls-universe.info regularily
2. Check out http://www.xdocs.ls-universe.info
3. The Docs are in the Docs folder (or always in the Module Archives (.zip) in yoour Litestep/Modules/Archive).
If they (xLabel.chm) aren't in the Litestep/Modules/Docs folder, then see 4.
4. Update NetloadModule2 to version 2.5.0 (maybe even the LSBuild) -> there's a link at http://www.ls-universe.info

Good luck!
