Can't use player WhenUsave missing

[Tizio]

Uninstall BSplayer, delete all its forlders (C:\Program Files\Webteh\BSplayer\ and C:\Documents and Settings\USER_NAME\Application Data\BSplayer\), plus delete all WhenU Save folders (if I remember right it's something like this C:\Program Files\Save\). Then try to reinstall it.
Otherwise instead of only deleting Save folder, use an anti adware/spyware tool, for example Ad-aware from Lavasoft, before you reinstall BSplayer
