C-Rio download issues

[dungeonmonkey]

when i want to download the code to the robot, it seems to succesfully complete the task, but when i restart the control system and hook it back up to the classmate, it says that there is no robot code. i have already formatted the C-Rio correctly and have tried putting the default code on (although it may or may not be last years default code). Are there some coding changes that i am unaware of? originally i thought it was just the classmates configuration settings, but if that was the case, shouldnt the jaguar lights still become solid? pls help!!!!
