Very interesting error, I've never seen such one.
By any chance could you attach your project?
To attach a project archive, please refer to the following discussion.
The displayed editor mai.c file has not been saved. So, it looks like a pin or circuit design issue.
When you have a question, please tell us your environment such as which CPU and version of Creator you are using.
Providing your project would be best. However, of can't do that, provide the "TopDesign.cysch" would be a good start.
