ProTools 8.0.3 compatibility - release notes from Digi
http://akmedia.digidesign.com/support/docs/ProTools_803_Read_Me63871.pdf
Incompatibility of Apple Logic Pro 9 or MOTU Digital Performer Running as a DAE Client with Pro Tools HD 8.0.3 (Item #119902)
Due to unforeseen technical issues, the newly released Pro Tools 8.0.3 software will no longer support Apple Logic Audio or Mark of the Unicorn Digital Performer running in DAE mode. Attempting to play back will result in no audio output. Record- ing audio in Logic will yield the error “Saving spool file / Entry not in queue. Result code = -1.” Users of both applications can still take advantage of Pro Tools CoreAudio drivers and use the Pro Tools HD system as hardware I/O. Pro Tools 8.0.1 will con- tinue to be made available in its current form to Avid customers who are using Logic Audio or Digital Performer in DAE mode for the foreseeable future.
I'm posting this as I know there are a lot of Digi hardware users here, like me, that may need to know about this. From what I read from this paragraph above is that if you need to use "DAE mode" stay with 8.0.1. I also think, from the way it's worded, that they are not promising to fix this issue any time soon either.... Very sad.
I hope this helps other Digi hardware users out there who were wondering about updating to 8.0.3.
Cheers
