You are still using old version of toolkit. You should be using this ... Latest test build - 2.8.2.0 (rev 4270354d) No I updated it but it still gives the same error. However in the updated version when i click no the toolkit tries to save a .dlc file Take a look at the version number in the application title of the screen shot you posted. It is not the current test version. After that screenshot i upgraded the toolkit. It is v2.8.2.0 right now. Also i put the files on drive maybe they will be helpful : https://drive.google.com/open?id=0BwIZazI3MCIyZUxuMmlpTGVBWEk
