Need help with Midi Beat Clock

[CIPHERM8]

Hello friends, ok Im having a problem with my MIDI beat clock on Pro Tools LE. I have my Synthesizers hooked up to my midi out port on my DIGI 002 and when I first installed PRO TOOLS LE, in the MIDI BEAT clock I saw both MIDI outs MIDI 1 and 2. Well then Yesterday I powered my computer down (PENTIUM 4 2.8ghz windows XP home) and when I turned it on the midi beat clock only had my computers soundcard as a choice, so I uninstalled pro tools and installed it again and there it was again the DIGI 002 MIDI out 1 & 2, well here it is another day and they are gone again. How can I get the MIDI BEAT clock to show me the DIGI's MIDI outpuits again. without having to uninstall and reinstall again. Im trying to syncronize my keyboards to where when I press record on my DIGI it starts up my keyboards sequencer. PLease someone help. Hop this made sense. Thank in advance.
