iMacros: How to make it ignore proxy prompt?s?

I have created a working imacros bot. I use proxies and whenever a prompt comes up (pictured below) for the username/password, it says "stopped" in the lower-left corner and it all stops working.

If anyone knows how I can get around this, please help me out. Thank you in advance.
