Virtuemart - error when removing a product

I just installed this template and when I try to remove some product from Virtuemart I get the following message:

Could someone help me?

Thanks,

I just installed in another server and did not get any errors!
I'm using WAMPSERVER 2.0. Could that be the problem?

The problem could be PHP version or server configuration, notice messages are not warnings so probably it is only PHP configuration issue.
