Howdy all

Fireface 400
Pro tools 9
Windows 7

In PT9, when I try to use the playback feature with pro tools (or even try to select a different part of a section to play) I'm hit with the error message "Access violation occured, unable to read location 0x66567DF9". Any idea whats' going on?

When I use the FF400 in Cubase,  using the FireFace Mixer the only sound I am able to manipulate are the two channels designated for the headphone/speakers slot.

Perhaps I need to re-install the drivers?

Thanks in advance!
