[pstricks] problem with package bardiag

[kris]

I've installed the latest version of miktex. When using the bardiag package to genereate bar graphs I receive an error message: 

! Package keyval Error: labelstyle undefined.

See the keyval package documentation for explanation.

(for more info see the log file in attachment.

Does anybody know how to solve this problem?

Regards,

Kris
