Cannot display find tab(177)

When using the help option from start/help. I go to the wizard at the end I get this message ‘Cannot display find tab(177)’. I did a search in the technet site and it mentions that some *.pst files in the windows\help directory may be corrupt and it asks for those files to be deleted and then start the help wizard again. So I deleted those files and restarted the help wizard and I still get the same message. Any suggestions??
