I recently upgraded JTX 9.3.1 with service pack one and now I get an error when I try to validate a custom step, such as launching arcmap using an alternative MXD, I get the attached error message. Even if I try to create a new step using the custom desktop objects, I get that error on all of the JTXDesktopSteps when I try to change the properties on it. It seems to work fine if I uninstall JTX and reinstall JTX Admin. Any help or suggestions would be appreciated. Thanks
