now im pissed off!! corrupt .als

[tigus09]

I Get corrupt files when i put my session from my Mac Book on a USB key then transfer it to my iMac that runs the same version of Ableton. I'm pretty new with Ableton and have no idea what you guys\girls are talking about when it comes to file order or whatever. Great news is the files still work on my Mac book bad news is i can't play it loud off of my iMac


Thanks ahead of time for any help
