QuietSeb:
It seems we're both online 8) !
My 1st idea was yours but I've asked explorer (I quite never use it, I prefer Windows commander) to look for _bspst$_ and it coluldn't find it even if I could see it. Of course, when I exit BSplayer, the directory is removed, then I've created the directory again, and the command din't work neither.
An other way would be to open the Windows startup menu, select Run and type:
In the windows cosole window that appears, type:
to look at the environnement variables and read the USERPROFILE value (it should be the current directory). If it is, type:
and select
Local Settings\Temp then remove the
_BSPST$_ directory (Quit BSplayer before, if open)
