Error Code

Hello, I am using rapid miner as part of an assignment for one of my classes, the class requires me to export the file in order to show my work and I am having issues doing this. Whenever I go to rapid miner I am able to get to file through the local repository under the Repository tab, however, whenever I try to use the exported file it gives me the same error message. I am attaching a screenshot of it. Please understand that I know very little to nothing about the in and outs of rapid miner, nor am I particularly tech-savvy, so if you could explain the details in the simplest of terms and step by step that would be fantastic.
