I have two separate installations of imagevue on my site that work fine.

I have installed a third by copying and uploading all the same files from the first installation. The only thing that is different is what's in the content folder.
However, all I get is a blank page with this latest install.

I've unistalled and reinstalled the flash player and reinstalled all the imagevue files but still can't get it to work?
