Cannot access menu options in demo

Hello...I downloaded the ecommerce template. It uploaded successfully but now when I click on the features menu option or any menu option, I get an error message stating that the page cannot be found. Please let me know if I am missing something.

Also, where can I go to change the menu names? I tried changing the styles menu option to About Us, but was not able to do so in the Menu section of the site. Please advise. I dont work with templates too often, so please excuse me if I am asking stupid questions. Also let me know if you need additional information.


Thanks.....

If you downloaded template more that 2 weeks ago, download it again. There was VM update that caused error 500 on category pages.

BTW. this is the fix , execute this SQL script on database:

UPDATE #__virtuemart_configs
SET
config = REPLACE(REPLACE(REPLACE(config,"p.product_name","l.product_name"),"c.category_name","l.category_name"),"m.mf_name","l.mf_name");
