Aye try that, or maybe holding down ctrl+command+option+shift as the application boots (on a mac). restores PS to default install. No totally sure but doing this might lose a few things like panel prefs/actions/selections/swatches etc - but you can save them off first. If on PC I'm sure there's an equivalent.
If that doesn't work then a clean install might do it.
