Virtuemart not working after update

[oturpin]

Hi, Since I updated to Virtuemart 2.0.26d I get errors.

I get this error when confirming an order on the frontend
Fatal error: Call to undefined method VirtueMartModelOrders::getMyOrderDetails() in /home/leader/public_html/components/com_virtuemart/helpers/cart.php on line 1072

And this error when confirming on the backend
Fatal error: Call to undefined method VirtueMartControllerInvoice::checkStoreInvoice() in /home/leader/public_html/administrator/components/com_virtuemart/models/orders.php on line 1375

Yet the order is still placed when confirming the order...

Using Joomla 2.5.17
