Where’s your SWF folder located? Are links set up properly in config.php? Are the links set up properly in client.php? Did you edit the external variables links to your hotel link?
Which CMS are you using? On the surface it doesn't appear to be an issue, but I've tried setting up Brain before and had the same issue. Switched to the good ol Rev and fixed the issue entirely. Not sure if I missed a step or not on the Brain config, but was a headache.
check all the links in ur config.php and make sure u have filled the links in client.php aswell or post them here most likely the issues being caused by a typo in a url or something
