user3648: I encountered a error whilst downloading Bitcoin-Qt on my Macbook version 10.6.8; it says "Failed to read block"
How do I fix this error without losing the bitcoins currently in my wallet?
Your assistance will be greatly appreciated.

user2526: If you backup the wallet.dat file, then you should be able to remove everything else, and then Bitcoin-Qt will redownload the block chain.

user208: Start the client with the -reindex command-line option.
