[Typo3-UG UK] Photoweb Extension

[Stuka]

Dear All!

I did install the Photoweb Extension, but I received only database error
messages.
The error messages:
Warning: Supplied argument is not a valid MySQL result resource in
c:\aktivweb\hometypo\typo3conf\ext\kh_photoweb\pi1\class.tx_khphotoweb_pi1.p
hp on line 1108

Anyone have a idea, what's wrong?
