Subject Re: CRC check failed
Date Thu, 13 Aug 2015 23:16:32 GMT
Hi Benjamin,

Have you tried LogFormatter to check the file? I guess it won't work if your file is really
corrupt, but it might be worth a shot. Unfortunately, I'm not aware of a way around it other
than deleting the file and and losing at least part of the transactions in the log.
