I have recently purchased the Joomla! 2.5 VirtueMart Template - 002049 and had a couple of questions. The modules Best Sales (position-56) and Postion 0 (position-0) are locked and giving me the following error:

Check-out failed with the following error: The user checking out does not match the user who checked out the item.
You are not permitted to use that link to directly access that page (#63).

Also on my home page http://shigadigsample.com/Joomla/ I cannot figure out how to remove the TOP PRODUCTS.
Thanks in advance,
