Seriously, this is just scaring me ********. On Sunday, I discovered that my entire keyring was deleted - all passwords and certificates - gone. Next, all my "Recent Files" in applications such as Adobe Photoshop CS4 and After Effects CS4 were completly wiped out, and after that, they are no longer saved there anymore. Yesterday, all my "Places" in the finder sidebar got wiped out. Also, search isn't working properly. As I just logged in to check my mail, a wizard popped up, asking me to set up a mail account! So WTF is happening? I've tried looking into the ****** OS X console to find any interesting error messages, but as Adium spams the log, I'll be sitting around looking for days after a snippet to post for you, so I ask; do you have any idea what these symptoms mean? I'm planning to back up all my important files and do a "delete and install" in about an hour, because I'm afraid my personal, important files will disappear soon.
