Thanks for the reply Jack, yes that is the error message I get.

My work-around seems to do the trick. Change the playback engine to the 11R, then close and reopen PT. Then switch the playback engine to 003, and then both the 003 and 11R load.

I even downgraded the drivers, which is difficult because at this point the driver that for the 003 that is PT 10.3 compatible is not supported with my version of OSX 10.7.5.

So in an effort to keep this rig running for the next 10 years, I'll just not touch anything... and use my workaround. Even if Avid comes out with a fix, it won't be compatible with my old OSX.
