I want to try the latest version of MRL (1.0.1938) on Azul. I am currently using ver 1.0.1859. I think I read in an eariler post that you don't have to delete everything in your MRL folder. You can I just delete the myrobotlab.jar and copy in the new version? Then run mrl.bat. Now that we are using programAB, gestures, and different speech, The mrl folder has even more folders. What is the right way to upgrade?
