All the documentation shows the Port names as:
mtr_S1_C1_1
mtr_S1_C1_2

But my tab, running version 1.46 of RobotC shows it as:
MotorD
MotorE

Is this a problem?

I suspect the Configuration Wizard is messing up my #pragmas because when I use the wizard the programs won't compile: I get errors that say the compiler doesn't recognize MotorD and MotorE.

Did you have an older version of RobotC installed before you installed 1.46? If so, did you completely uninstall the older version before installing 1.46? I have seen these kinds of problems when someone installed a version of RobotC ontop of an existing installation of RobotC.

I did have an older version - the one (1.40) that came with the kit. So I just uninstalled it and now Windows can't find the executable for version 1.46! Help!

They do not live side by side. That is part of the problem. Now that you have uninstalled RobotC, you need to reinstall 1.46. However, I suggest going into the Program Files folder and deleting the Robotics Acadamy folder first to make sure that when you reinstall 1.46 you have a clean install. Then everything should work correctly.

Thanks, Jeff. That did it.
