Ok you should be good to go, what I did was the following:
In your index.php I changed all instances of:
if (JRequest::getVar('option') == 'com_virtuemart' ) {
} else {
To:
if (JRequest::getVar('option') == 'com_virtuemart' ) {
} else if (JRequest::getVar('option') == 'com_rwcards' ) {
} else {
This accommodates for the third party component you are using and says not to use lytebox CSS or javascript when this component is running.
