no details page products after reinstall

[emel]

guys,

after 4 days i am about to give up...

bought a gavick template with integrated shop with dummy-content. everything worked fine, until i added another language. (pre-installed data conflicts with new, default language).

then: re-install the entire vm packages. + language packs joomla and vm. everything looked great in the backend, no red errors, modules showing vm cats, etc, etc.

but.... on the front-site: detailled pages are now invisible....

switching on the bug reporting gives this:
        vmdebug self::$_jpConfig->lang nl_nl
        vmdebug vmTime: loadConfig db no: 0.00399494171143
        vmdebug Start used Ram 6.5M
        vmdebug vmTime: VirtuemartControllerCategory Finished task : 0.0894749164581
        vmdebug End used Ram 9.5M
        vmdebug Peak memory peak 9.75M

What to do now? on a tight schedule.....
