Error Box When Downloading Programs


I am quite a newbie at RobotC, so I just wanted to apologize profusely beforehand if this is a really stupid question. When I try to download programs, this error box shows up, which I do not understand at all.

At the bottom, it says VexI2CEncoderVelocity, which I am guessing has something to do with IMEs, but I have none plugged in.

What does this error mean, and how can I fix it?

I need to ask a few questions.

Which version of ROBOTC? ( V4.52 is the latest. )
Have you updated the ROBOTC firmware? When a new version of ROBOTC is released you need to make sure the ROBOTC firmware that is in the cortex matches the requirements of the new version.

Does this happen after you start the program?

Perhaps start a private conversation with me to answer these questions as the tech support forums do not allow members to use follow up ports.
