Mbox2 doesn't show MIDI ports available after PT8 upgrade..

[Kmi]

Hi Mr. Admin,

I followed your indications and when I reinstalled PT7.4 the I/O ports were available in the MIDI Studio setup and working properly.. so I proceded to unistall just the application (PT7.4), and then I reinstalled PT8.0... but, the I/O ports disappeared again.. I don't know what could happened because it was working very well.. please!.. I need help with this issue.. I'm going crazy!!..

..oh! and thanks for your attention to this matter..

In few words, my system (PT LE 8) was working fine until an OS (Vista Ultimate) crash down. After this I reinstalled PT8 but I realized that the MIDI was gone.. There's no available MIDI ports in the MIDI Studio. I used the PT nuke to uninsatalled the software, and then installed PT 7.4 from the Disc. After this I unistalled only PT LE 9(7.4), and reinstalled again PT 8.0.. but neither PT8 nor REASON showed the MIDI I/O ports from the Mbox.. I don't know what else can I do... I'll appreciate any help!!
