Bader, fire up regedit, look for HKEY_CURRENT_USER/Software/Naturalpoint/Naturalpoint/V 3.01GX (or whatever version you have installed)
then look for the 'viewlimiting' key and set its value to 0 - that should reenable the 'dead 6' view
Please note that the NP application MUST NOT be running while doing this (else it promptly resets your change)
