impossible to eliminate orders, EU VAT ID

[melissio]

Hello,

I just installed the "com_virtuemart2.0.0_RC3_Pre_i_extract_first.zip" but I noted itsn't possible to eliminate the new order, following the error:
Fatal error: Call to private method VirtueMartModelProduct::updateStockInDB() from context 'VirtueMartModelOrders' in /home/mpind/public_html/administrator/components/com_virtuemart/models/orders.php on line 731

It isn't possible to show tha vat also and  the system don't calculate its to the checkout.


First to install the new release I  uninstalled all "virtuemart1.9.8.RC2M_extract_first.zip" aio also


thanks
