"my Toolbar" went missing

Hi, I'm running CD X5 on a windows 7 machine. I had a custom "my Toolbar" set up wit all my most used tools and now suddenly it's gone! It is turned on in the menu (checked). I have unchecked it and rechecked it to no avail. I  have re-booted my machine and still nothing. I have no clue why it's gone but I can't seem to get it back. Any ideas for me to try?

Thanks

Mark
