It would be great to get help please.
I had been trying to verify blocks which were long since rebuilt, because i had neglected to run the client. I struggled to get it going again after various crashes and using Time Machine to help me out.
Having run Bitcoin-qt on my Macbook now for over a week, and seen steady rebuilding going on, today i had what i think was an external electrical problem and my Mac switched off. It's okay again, in fact automatically rebooted. However Bitcoin-qt would not start up again. I have tried all the previous remedies incl. time machine backups, although I turned this off once things started again before to speed it all up! so had nothing to restore except the .app, and to no avail I get different crash reports, if I try to run the old original version that had been working ok until today (0.8.5) - it reports:

Application Specific Information:

If i try to use the most recent version I get a different report.
Is there any obvious solution anyone can identify, and help me with?
Thank you.
