I'm having real problems getting anywhere in figuring out what's going on with this plugin.
Thanks to stuff related to the way URI are dealt with internally (that has changed over time) the additional component installation might fail. Please drop me an email at unDavide at the google email service you know dot com.
I've just checked the Support Form on my website and with horror I've noticed it returns an error, that was unexpected. Is that what's happened to you too?
