Help with Mbox *On Tiger OS*

[SGSeries]

Hey dudes, sorry if this is the wrong forum to post this in but there is so bloody many to choose from :/

Well, i had my MBox working fine with Pro Tools LE 6.4 and Garageband 2 when i was on panther...a couple of days ago iu upgraded my iBook G4 to Tiger, now my MBox won't work with either programs, i was just wondering if i'm the only one experiencing this problem or is there a way to fix it...do i have an up to date version of Pro Tools? i have the Pro Tools LE that came with the Mbox...v 6.1 i think, what updates are available to me at this time - only 6.4 or can i get a higher version?

Sorry if that's really confusing but im confusing myself with this now so...thx in advance for any help i wan't to get this sorted as soon as possible
