Hi, The probe is in space, a stable orbit around Kerbin, it has a probe core (Stayputnik Mk.1) - its got the basic antenna that you have at the start. I have rechecked and noticed that I do have some of the additional parts that come with RemoteTech2 - however I don't get the options to activate the antenna's and I can still control a probe in orbit without an antenna. I also don't get the computer options to perform maneuvers. This could be a bigger problem, I have noticed that although Mechjeb seems to work fine (module is there etc) - I don't get the option on the right hand side to bring up the Mechjeb options. I have tried this in a new sandbox mode. I have also tried to disable AV etc. I am not running the full installer though, instead just downloading and unpacking the folder to run from there? would that make a difference? Thanks, Craig
