IE JavaScript Errors

I've done a Fotomoto integration on my blog using the API. Everything works correctly in Chrome, Firefox and Safari, but in IE I'm gettring the following JavaScript error:

SCRIPT16389: Unspecified error.
fotomoto-min.js?1313534803, line 155 character 186

This is happening in IE9 and 8.

Could you advice what could be causing this?
