Mbox 2 w/Pro Tools 9 wont work

[reverendrambler]

Hi folks, Im in desperate need of help. Just lost my hardrive and now both my Mbox2 and Pro Tools 9 (crossgrade)wont work. The Mbox lights wont even light and up and when I try to open Pro tools the icon bounces for awhile and then does nothing. Ive attempted to install various different drivers as I suspected that was the problem ( Mac OSX 9, 002 and 003 family driver as well as the one from the install disc). I suspected that the issue may be with my operating system which is currently Snow Leopard 10.6.8. Other threads I found instructed me that I may need to install a combo update for the OS, which i did, and later I tried upgrading Pro tools to 9.0.5 thinking that may be an issue. Everything worked fine before losing my HD. Please help, I officially dont know what to do, Im thinking that I should try and downgrade my operating system somehow back to 10.6.7 or earlier.
HELP ME PLEASE

thank you
