Hi, Well Iâ€™ve combed the forums but canâ€™t find a solution for this one: A few months ago I moved from a Mac G5 to a MacBook Pro running Lion 10.7.4. I updated my Logic Express 9 to Logic 9.1.7. Iâ€™d been able to create new projects and reopen them just fine. (These projects are simple voice over audio recordings.) Reopening old projects created in Express 9 has required me to search for audio files â€“ a hassle but thatâ€™s okay. All of a sudden Iâ€™ve been unable to open any project. If I double click the Logic project icon in a folder, Logic launches, the file says its loading, but nothing appears. If I Launch Logic from the Dock and key command > O, find the file and click Open the same thing happens. After this chain of events occurs and I double click the same icon, there is a white flash on the screen indicating that nothing is going to happen. Then Logic freezes and I have to force quit. Iâ€™ve noticed that when I save a project after bouncing a region I get an error saying that Logic can't find the original file. Weird. So then there are two files and at that time theyâ€™ll both open. Could the problem be that the 9.1.7 update was only temporary? I wasnâ€™t charged for it. Or is it something else? You guys have been so helpful in the past and Iâ€™m at witâ€™s end.
