Spider Exception: "Controls created on one thread cannot..."

I've just downloaded this tool to try it out. But I am getting this error when I try to crawl my site:
http://tomaterpaatredje.dk/

It says: "Controls created on one thread cannot be parented to a control on a different thread. Failed."

I have made no adjustments to the settings, I simply installed it and tried to crawl my site.
I'm on windows 10 on the latest version of Excel.

Am I using this incorrect or?

This is a bug that we need to look into.

Just released a fix for this: http://links.seotoolsforexcel.com/latest
