I keep getting emails that my PMs are full, but I just checked (again) and nothing is there. Yet in the top right corner of the says "Private Messages (Unread 0, Total 200)
Did my PMs not delete or something? I'm assuming people are trying to PM me and it thinks my inbox is full, yet it's cleared to me.
Try the following to see if it works, In Private messages window there is an option in a bar that says "Empty Folders" Click that option. In the next window you will be given what folders to empty and the option to keep any unread messages. If you dont want any messages simply uncheck "Keep any unread messages" and then delete.
