First off I apologize if these questions have been answered before, I did try and search with no luck. I have been trying to get mechjeb to operate properly all day with little luck. First, I tried the 2.0.7 version, but every time I tried to use the ascent assist, it never put me in a parking orbit, just kept going, long past the orbit of the next few plants. So, I then uninstalled KSP completely and installed the 1.9.8 version. I had varying luck with it. I was able to get mechjeb to put in a 100k parking orbit a few times with no problem. But ran into an issue where after I was in parking orbit, none of my (non-mechjeb) commands would work. I could not increase thrust, rotate, or anything, map commands did work though. If I messed with the ascent assist again, it would adjust the throttle, but the engines would not fire. This issue with my commands not being able to operate by hand I think leads to the next issue, after in parking orbit, I tried to have mechjeb land my craft. It would warp to the proper location, tell me it was thursting, but there was clearly nothing happening. I also tried to have mechjeb put me in a transfer orbit to the mun, it would warp to the right spot, tell me its firing my engines yet nothing was happening. My last attempt with mechjeb before writing this post, I had my original issue with the ascent assist not putting me in orbit, but continuing to send me out to some far out galaxy. (still using the 1.9.8 version) I have the steam version of the game, I am not sure if that has anything to do with my issues. I am using no other mods but the downloads that are linked from this page. Any insight on how to fix these problems would be great. Thank you.
