the best fix for that is to soak it in lighter fluid the digi hardware that is and light it on fire. that usually works for me and then it's up and running. lol joking but i have the quad and same 10.8 but stuck with protools 8 and the cs3 update. i don't know what to say maybe someone will know. ive seen many posts round the board about 8.1 problems so i never went there. that's why i always have another daw on my mac like logic or something if pro tools starts crashing. someone will know, hang in there and keep checking back. i know your frustration! it sucks to really be on a roll and then end up being a repair man for 5 hrs and by the time it gets fixed you don't even have the energy to want to do it and lost the creative spark.
