Hi,
I am seeing that you haven't properly setup the Virtuemart yet.
This is the error message i am getting when i try to reach the Virtuemart page:
Attachment ScreenShot2014-01-29at4.16.55PM.png not found
Please add a sample Category and couple Sample products to your Virtuemart. Make sure everything is working, then enable our module.
There shouldn't be any problem then.
Regards,
Support
