Robot Mesh with Vex Legacy

Hello, forum-goers!

We have been operating a robotics class using the legacy cortex (we use V5 in a competitive club.) We have been having trouble downloading programs to the cortexes (cortexi? cortexs?). Some work perfectly, but others don’t at all; the program just does not run. Is there a reason for this? Thanks!

To confirm, the same program being downloaded with the same computer and same USB cord to different Cortexes fails?

Yes. It has worked on multiple robots, and all of the cortexes are up to date.

Try checking the “Force Full Download” box in the Options menu and see if that convinces any of your recalcitrant units to behave.
