An error occurred with virtuemart

Hi!
I has been installed the J1.7.3, then install OT Appoz template and then install virtuemart 2.0.
Everything going well, but when I try to look a goods categories (front end - click on menu item "Category" - assigned to "category" in virtuemart) an error was occurred:
---
Fatal error: Call to a member function getResultsCounter() on a non-object in ...skipped...templates\ot_appoz\html\com_virtuemart\category\default.php on line 181
---
Also, the main page of virtuemart in frontend, when I try to show all goods by developer (developers, goods and categories are in the base), follow error occurrs:
---

Please help me to investigate this problem?

Hi,
please remove the folder com_virtuemart and mod_virtuemart_cart in templates/ot_appoz/html/.

Thanks!

Thank you, it's skipped the problem but doesn't solve it.
I'm already done it and any error disappeared.
But if remove this folders the page doesn't looks good.
Anyway, thanks
