As the subject says, I'm trying to run Text Editor for Casio FX-9860G on my fx-9860G II SD. When I do, I get:
Illegal Code Err
I tried deleting it and reloading it. No change. I tried copying it from storage to main memory but it won't go there. I can copy it to the SD card but can't run it from there.
What am I doing wrong?
