I can not make her shop

VM 3.0.12
Joomla 3.4.6
I installed virtuemart 3.0.12 Joomla 3.4.6 was all set, but not the vendor. I enter all the data, but when I click save or close, nothing happens. If I move to another menu and return the data is erased.
This is the message that appears.
The user with virtuemart_user_id = 393 is Set as vendor, but has no referencing vendorID.
Initially I kept the data of Super User installation, but I wondered Name Username etc. and when I entered still did not save. Then I created a new Super User but nothing happens.
I also created a test product, but the product page does not appear the figures of cost and price Total VAT. I can add it to the cart, but the prices there are.
I installed virtuemart on a test site and existing on a site created specially. There works perfectly, but I need that functions on the site. My feeling is that there are problems with users of Joomla and so you can not create the vendor.
Maybe it's a simple problem, but after having tried everything are still at the starting point. If someone can help you are welcome.

Thank you for not having responded to me. I solved it by himself.

Plus it could only have been a methodical checking of your configuration ...  what could someone deduce from your post?
the answer would have been go back and double check everything for logic and config.
