The operating system held off interrupts for too long. If this occurs frequently, try increasing the "H/W Buffer Size" in the playback engine panel. (-6093)

...did all that.

I get this error when trying to play back a session that I was mixing last week at a different studio than my own.

This studio is running a 002 on a DP 1Ghz Mirror-Door / 1GB RAM - FW Maxtor HD

I went back there today to finish the job. However, at some point during the week, another user had updated their system to OS10.2.8

The same exact session was working just fine last week prior to this update with no problems whatsoever

This particular session has a DV video track playing out through the Firewire port. The session will play fine as long as I don't select the
"Play DV movie from Firewire port" in the movie menu and simply let it display in a window.

I have run Repair Disc Permissions, trashed prefs, unistalled & reinstalled PTLE6.1.1 - I even created a new user account (admin) on this machine and did a fresh install of PTLE6.0.2 up to 6.1.1 - still no luck.

Is there any easy way to downgrade back to OS10.2.6 without having to initialize the drive? This exact session was running great on 10.2.6

Thanks,
