Hmm, and why did you buy VirtueMart Extension for JoomSEF 2.x if your are using JoomSEF 3.x?
What is your order ID?

Hello,
My order number is 6301 ,i thought the last suffix should be 2.x ,the site i am going to use it at melodi.no ,can you please send me the 3.x version,
I also sent an email to support too,
Thank you ,

We have switched the product for you. :-)

Hello,
Now it installs but giving an error and my store is being offline,
Fatal error: Call to undefined method JoomSEF::_getMenuItemInfo() in /home/melodin/public_html/components/com_sef/sef_ext/com_virtuemart.php on line 180

Please help,

You will need to upgrade your JoomSEF first as well.
As you can read at:
VirtueMart JoomSEF Extension
it says:
This extension requires ARTIO JoomSEF 3.3.x or newer
