has anyone seen this with Pro Tools?

[mac's my homie]

I've been using Pro Tools LE 6.4 w/ Mbox on an iBook G4 flawlessly for 2 years. I upgraded from OS X 10.3.9 to 10.4.8. Now when I open Pro Tools is says "Dididesign hardware is in use by another application. (-1133)" It won't open past there.
I thought maybe there was an upgrade for 10.4, but I didn't have much luck looking for one online.
Any advice would be greatly appreciated! Thanks!

To be running PTs on 10.4.8 you need to have PTs 7.3. Using Tiger you need atleast PT 7x.

OP -- always always always check digi's compatability pages (http://www.digidesign.com/index.cfm?langid=100&navid=54&itemid=23954) before upgrading osx.

I was afraid of that. I guess I'll just have to upgrade. Thanks for the advice!

do you have another program like reason running before you try and open pro tools? in one of my classes last semester i would get a similar message if reason was open first for some reason. if that is not the case, i have no idea.

no, I quit all my programs before running. Thanks anyway!
