Thanks Analogous, Kartu and Mekk for the info! I'm trying to either get admin rights on the PC I've borrowed or find another PC to use.
One question: Since I don't have easy access to a PC, that also means I don't have easy access to the PRS+ Uninstaller. If it turns out PRS+ is problematic for me,
will a hard reset restore the original PRS-350 firmware? Or will running the latest Sony firmware update overwrite PRS+ and revert me back to Sony firmware?
Thanks!
