Hi, sorry for the late reply, looks like your topic has been missed.
The solution is pretty easy though, do this:
through your FTP, change the name of this folder name from:
/templates/YOUR_TEMPLATE/html/mod_virtuemart_cart
to
/templates/YOUR_TEMPLATE/html/mod_virtuemart_cart2
And you will start using the original Virtuemart Cart module.
