My boot drive was starting to fail. I ourchase a new drive and cloned it with the Seagate software. Everything appears to nbe there. When I start WLMail

I get the message that Mail must close due to a corrupt calendar data 0x8E5E0247. All my emails .eml etc appear to have been copied to the new disk as well as the appropriate WLM directorys. I uninstalled WLM 2011, removed the Calendar directory, rebooted, installed WLM 2012. Still fails with the same error message. Each time I remove the 'calendar' directory and then start WLM it re-creates the calendar directory then fails.

Hardware details added later   
Computer: HP "HPE 390t i7 X980"
