I did not say to delete the entire workspace. I said to delete any ` __lib__ \xod*` folders in the workspace. You can try uninstalling and re-installing XOD to get it back.
pwm-write node is supposed to have PORT, DUTY, and UPD pins, not 3 PORT pins. You should never be changing built-in nodes. You can make copies of any node and make changes to your copy.
