Pedro - are you attempting to "Run" the code using the arrow in robot main.vi, or are you building then permanently deploying it to your robot?

In addition, you don't really want to be switching users. It's better to deploy the code then log off the developer account and log into the driver station account. Simply "switching users" leaves program running in the other account that will slow the computer down. I can't tell if that's what you're doing, so can you clarify?
