My ibook has recently (the last 4 days or so) has been doing some strange things. First of all, the mail client keeps asking me to set it up when i start it up, as though it has deleted my 2 email accounts i use with it. Secondly, Disk images are failing to mount, giving me the message "verification failed". Finally, WMV i use that are protected by DRM are not opening, giving me the message "cannot open the file. Very the path and filename and try again" This all started happening after filevault asked me if i wanted to "clean up" the user area. While it was doing this I gave up, afetr 15 minutes, and stopped it by holding down the power button. Everything then started to happen. What should I do? Is a reinstall in order here?
