You know, I had the same problem!
I emailed the guy who created it and this was his response:
we are sorry we cannot help with the error you are receiving, as it looks like some kind of internal server error, which would require direct access to your web server in order to be tracked down and solved.
You may want to seek help from your website developer, or use WordPress community services; before doing that, please make sure you followed carefully the instructions for using the plugin.

I think I might just delete it since it doesn’t work:(
I added that and it didn’t fix my blog. Now I found another bug! It’s not posting properly.
