I have the same problem and have followed the suggested steps (download a certain file or reinstall). The download did not solve the problem, and reinstalling only works temporarily.

JJ it was you !  And now that you mention it I might just have done that and forgot I did.  Anyway you sound like my wife scolding me again for my stupidity.  Hey I'm not the sharpest knife in the drawer, know what I mean ?
