ST9 Windows 10 Self Guided Course Lesson 7 Patterns Activity

Having an issue with lesson 7 on the self guided courses. The patterns activity file could not be saved because of an error writing properties to the new file. I was wondering if anyone had any ideas as to why this is happening. ST9 on Windows 7


Update: Tested and it seems to only be happening in this one case with this one computer. Still any insight would be appreciated


Thanks for any help.
