Nero 7 multimounter problem

i installed nero 7 then multimounter according to its readme instructions. everything looked fine just like with nero 6, i opened properties for the drive - volumes tab with sessions list was there.

but now i noticed that there is actually no way to switch to any of the previous sessions in a multisession cd. i can choose any of the sessions, press apply - the check mark does move to the selected session. but when i close the property sheet only the last session of the cd is available in explorer - it does not switch to displaying the selected session.

i never had this prob with nero 6.
