Changed logo Shop and Buy

Hi I tried to changed the logo in the Shop and buy template under VirtueMart - Shop - Vendor - Image information.
But now I've messed up the used url and now it give the following indication:

Warning: sprintf(): Too few arguments in /customers/8/1/8/zoetekoek.co.uk/httpd.www/store/administrator/components/com_virtuemart/helpers/vmtext.php on line 138 Warning: opendir(components/keys): failed to open dir: No such file or directory in /customers/8/1/8/zoetekoek.co.uk/httpd.www/store/administrator/components/com_virtuemart/helpers/vmcrypt.php on line 92 Warning: opendir(components/keys): failed to open dir: No such file or directory in /customers/8/1/8/zoetekoek.co.uk/httpd.www/store/administrator/components/com_virtuemart/helpers/vmcr
...

How do I chang it back to the original and then I'll just replace the logo.png.

Hi,
this is VM error not from Gavick products.
I can only guess that one of folder is missing.
Check on http://forum.virtuemart.net/

Ok, I'll look there, but it is there where the logo of your template shop and buy was used. When I changed the directory.

depending on used template color style:
templates/gk_shop_and_buy/images/style1/logo.png
templates/gk_shop_and_buy/images/style2/logo.png
templates/gk_shop_and_buy/images/style3/logo.png
