Disk image not recognized
I recently upgraded to Lion and now I am no longer able to open a disk image created under the previous system that contains important documents. I have read some older threads on this issue and nothing seems to work. Disk Utility and Time Machine are not helping me. This is terribly frustrating as I created this disk image to keep important documents under a passcode and now can no longer access them. Any help or suggestions would be greatly appreciated. Thanks so much.
