Looking back I have to wonder if you are using the comma as a fraction separator. For example, in the US, the number 1/4 is written as 0.25. In other countries, 1/4 is written as 0,25. Is this true in your case? If so, this is the reason for the syntax errors!

To get around this issue, go to the settings and change the separator from comma "," back to period "." Then open the source file and try checking this time -- it _should_ work. Once the check shows no errors, you can exit the source file (on the calculator). Now, as long as you never open this file again, you can change back to comma mode if you want.

Let me know if this fixes the issues.
