SpamSeive 2.7.4 Crashing

Today I have noticed that my Spamseive 2.7.4 has been crashing upon its initial start up. I have done all the typical system things like fix permissions ans check for disk troubles. I am a bit stumped can someone offer any insight into a fix tor this? this is my crash report:

SpamSieve’s corpus file was damaged, perhaps due to a crash or disk error. Please try holding down the Command and Option keys when launching SpamSieve and then click Reset Corpus. You will then need to re-train SpamSieve:

Or, you could try restoring the file:

/Users/<username>/Library/Application Support/SpamSieve/Corpus.corpus

from a backup, if you have one.

Perfect! things are working well once again. Thank you for your prompt help
