Yeah, I get those too. A lot of the exchanges don't seem to have quite enough capacity for their APIs, so they return error pages pretty frequently. The error pages are HTML instead of JSON so the JSON parser doesn't know what to do with them. I need to catch those and print a more friendly warning message.

This looks like a duplicate of #62.
