Error message

Hi Alex, thanks for making this plugin! It is a great concept. However I can’t seem to activate it no my local XAMPP setup. I get the following error:

Fatal error: Uncaught exception 'UnexpectedValueException' with message 'RecursiveDirectoryIterator::__construct(/C:\xampp\apps\wordpress\htdocs/wp-content/uploads,/C:\xampp\apps\wordpress\htdocs/wp-content/uploads): The filename, directory name, or volume label syntax is incorrect.

Maybe this is a problem with the plugin? Or it could be a problem with my system.
