Unable to launch piplay

I am suddenly unable to launch Piplay and I am getting a Javascript error.

I have tried rolling back to a previous version, but the problem remains.

I have attached the error message.

I am unable to use the support link in Piplay as I cant launch it.

have you tried a clean install of piplay? Just check the box clean install at start of installation

Thanks, that did fix it. I was hoping to fix it without losing my settings, but at least I have it working.
