Frustrating problem

[Edvinas]

Hello,

I'm having a pretty frustrating problem over here. I installed Joomla and used gavick's yourshop template with VM 2 implemented, though it didn't worked properly, so I uninstalled it and reinstalled again. Now when I click on category layout (parduotuvė) I get http://brite.lt/index.php?option=com_virtuemart&view=virtuemart&Itemid=181. If I try to edit template settings I get 500 - Layout "" not found error, please help me out with this.
Website URL: http://brite.lt/index.php
Thank you...


P.S I would install Virtue Mart 1, but I had serious issue, I had set up everything and after a few hours website just disappeared, nothing seemed to be working, except a few backend menus.
