Ok so one of my sessions screws up pro tools and produces the runtime error, so perhaps the file is currupt? But now when i load my session the audio doesn't output even though the outputs for my channels are set to interface 1/2 but if i hold alt and reset them all to interface 1/2 it works fine, and my ROCK AMP LEGENDS plugin doesnt have the same setting as before... but the autotune plugin still doesnt work, my melodyne brige loaded and booted melodyne but when i removed the bridge i couldn't put it back on the track because it gave me a dae error. Thanks
