I get a message saying "Can't save student file" at the end of a problem

1. This is probably caused by the student file being write-protected (we need a better installer script -- it's our bad!)
2. Go into directory MERGE-AI/Student Files/Data Analysis/Course/Students
3. Find the file that starts with your student name (for instance "by-sn-7") and ends ".stu" (not ".stu~")
4. Right click on this file and choose Properties
5. Uncheck "Read-only"
6. Click OK
7. Try running the tutor again.
8. If you get this message again, please email me

It labels the first label along the axis automatically for me, and then it won't let me label the second label!

• This is a bug we caught thanks to a tip from a student!
• There is one solution and one workaround:

• Solution: (requires a 6 MB download from online -- if you have a slow internet connection, use the workaround)
• Download DATutor.zip .
• Extract DATutor.exe from DATutor.zip (some browsers can do this automatically. Alternatively, try right-clicking on DATutor.zip -- if this does not work, you may have to download an evaluation version of WinZip (make sure to get the free version).
• Move DATutor.exe to MERGE-AI/CL Applications/Data Analysis, replacing the file already there

• Workaround:
• If you cannot download and install DATutor for any reason, use the following workaround:
• Always label the values along the X (left to right) axis before labeling the values along the Y (bottom to top) axis.

If you have any difficulties not listed here, please email me .
