Left and Right Drive Motors Teleop Disabled error

[4821 Vulcans]

Hi everyone,
We are using Labview and used the default code to start with. We have a 4-motor drive train with two Talon SRs controlling each side. When I tried to code another motor, even using a simple manual control where I type in an input, Teleop mode disables itself and we get an error text that says that an error occurred at the Left and Right drive motors: the loop contains too much code or something is starving the loop.

I'm wondering why this might be happening? We are able to use the drive motors but as soon as we try to send any input to the other motors on our robot, Teleop disables itself. We haven't touched the default code at all in any way except adding one motor as a test.

Thanks!
