issue caused because wmpband.dll is not registred go to program files>wmp folder open a command prompt there and run regsvr32 wmpband.dll .....that is it.
addons are not containing any hotfixes....yet. i will update them when i will have some time. so if u want also the updates for wmp11 u need to run wmp slipstreamer.
nothing is wrong..... nlite does what is called direct integration and doesnt create the teh uninstall folders and registry entries like in normal cases when u install a hotfix.
