I have a survey that works perfectly in Chrome, but when I click the 'Start Survey' button in IE 11 I get the following error message:

[object Error]

You should be able to see this at [link removed for now]

I have today's updated version of cjLib installed (and got the error with, and prior to this)

Also I've temporarily turned off my HTTPS and put error reporting to maximum... neither of those things seemed to help so I've put those back to how they were.

Any ideas on how to fix this?
