I have read and tried previous suggestions about missing folder and sub-folders. I saved all of my folders and sub-folders in a file and deleted the TB program (it had a bug). I reinstalled TB and imported from a previous version. All of my folders re-installed but without sub-folders. I've added IMAP to my POP server settings, made sure I'm looking in Unified folders, done multiple imports and cannot seem to import (or view) my missing sub-folders. I can view them in my saved folder, but can't open them because they are .msf files. Any suggestions would be appreciated.
