Trouble getting system started

[mphillary]

I'm not sure if it's the order I'm turning my devices on, but I cannot figure out how to get Pro Tools 10.3.5 to work on the first try every time when booting up. It tells me that:

"Your I/O setup has changed since the last time this session was saved. Check the I/O setup to see what's changed.

Some paths were made inactive because they could not be assigned to existing path definitions."

I haven't unplugged anything, just turned on my computer, then my Mbox then open protools and try to open a session and get this message all the time.

Have Macbook Pro OSX 10.8.5, refuse to upgrade OS for fear of losing Pro Tools.

Any help would be appreciated.

Hi! WelcoMe to The Forums

This message have plagued us a year now and even though we check the "over write" we get that message EVERYTIME we start PT. Both 11HD and 10HD even though nothing have been changed I dunno why and have not figured that out yet. However every song sounds right when we click "no" and PT fires up so maybe just ignore that message for now until someone swoops in here with a super duper fix for that

Best Wishes

I would definitely NOT check the box for "allow session to overwrite settings"(but do try both ways to see which works best for you). I WOULD open the IO setup page and select the Bus tab. Then scroll down. Anything on the left that is in italics, I would delete. Then, anything on the right side in italics, I would un-check(but yes, this is a thorn in the side)
