Are you using it in Flash mode by any chance ( _imageRotator.settings.jsScriptOnly = false
which happens when you uncheck "Use only JavaScript..." on the publish form?
If so, then it's Adobe Flash local desktop security that is blocking the license file locally. It only happens when testing 360 views on your own hard-drive locally, and I can send you instructions on how this can be resolved but we strongly encourage folks to not use Flash mode as it's not going to be supported in 3.5 (next version) as it's not supported by Apple products and it's gradually becoming an obsolete technology on the internet.
If you are not using Flash mode and it still can't load the license, please let me know the browser your are using (make and version) and it would be best if you could also send us your URL with the same 360 view or just archive it into a zip file and send to our email: support at webrotate360 dot com.
