Upgrading from Pro Tools 8 to Pro tools 9 in Lion?

Hey all,

I just purchased a new Macbook Pro w/ Lion on it. I installed PT 8.0.4 LE and got the error message: "installation failed to run postflight script for Avid Core Runtime". I'm assuming this error is because PT 8 is "not compatible" with Lion but does anyone know exactly what that error means and what is being affected by that?

When I opened up PT though it still runs fine as most people have discovered even though it's still not listed as compatible.

I am planning on upgrading to PT 9 as soon as my disc comes in the mail. Am I going to experience any problems upgrading to 9 because of this error during the PT 8 installation carrying over?

Thanks so much!
