Hi everyone,
 I purchase some of bitcoin last year and i stored it in my bitcoin-qt 8.3 and still keep updating it everyday. 3 weeks ago, I turned it off. About a week after that, I i turn it back and it keep crashing. I got my back up earlier therefore I delete my wallet and download the new one. Now after I downloaded and run it. It keeps saying faied to read block. I deleted and did it again but it still give the same error. What could I do now? Am I going to lose my bitcoin on that address?
Note: I remember the receiving address and I saved my back up on external drive.

PLEASE HELP. I DO NOT KNOW WHAT TO DO

I remember an error, about an invalid block last year. I am not sure, which Version of Bitcoin-qt was affected, but just updating Bitcoin-qt fixed it.

I just realized that it says Version 9.1 in your Title.
Have you tried reindexing?
Just start your Client from the console with "-reindex"

Don't worry though, as long as you have your wallet.dat you have your bitcoins!
