are you sure you did it right?
on a new windows install
copy thinstall onto the local hdd
then download the nesseccery files do a pre scan
install wlm and plus then do your post scan
then choose msnmsgr.exe as the only container
do wlm and plus at once so they count as one app
Note:also not it does need to be a fresh install or it will most likely Phail
