I've been using VirtualBox installed on my Mac Pro for over a year. I have a Windows 7 installation running on it. This morning, VirtualBox told me a new version is available. So I downloaded and installed it, ran it, tried to open my virtual machine and got a bunch of error messages and an "abort" button. OK, so the upgrade is no good. I downloaded a backup from last night of the Application. Ran that, tried to open my virtual machine, similar errors! So, I downloaded a backup of my virtual machine AND the application, still can't run my machine.
This virtual machine is vitally important to me. I have backups of everything and still I can't make it run. This very frustrating, I would really appreciate any help in getting back up and running. Thank you!!!
