Hey guys I need your help. Last night I was mixing a live recording I did of our band over the weekend. Here's what I did with the recording. First I cut each song out of the full live recording and made a new file for each song so that I could mix the songs independently. I put some plugins on each track, mixed some of the songs, saved them, and listened to them last night. All was well except for a few "logic crashes" , nonetheless the songs played fine. I ended up trashing the "crashed" files. This morning I try to play the songs and no sound. The main thing I notice is that all of the plugins have a slash thru them. I even checked an older recording we did and the plugins on that recording have slashes thru them as well. Did trashing the crashed files have something to do with this? I need your help to get things back to normal. Thanks.

In addition, when I try to change the I/O Buffer size or any of the preferences in the core audio I get the following error message. Error code -2 was returned by the Audio driver. If anyone can help me in rectifying this problem it would be greatly appreciated. Thanks.

I did an update on my presonus firestudio software/ firmware and this seems to have fixed the problem. Thanks.

Good. Thanks for posting the solution!
