Java FileNotFoundException

So a few days ago I installed the Rapidminer MLWizard extension. Upon installing it I tested it and it worked fine, now a few days later I am no longer able to use the wizard as it throws an "FileNotFoundException". I am getting the error when clicking settings->Automatic System Construction.
The log posts the following:
