just trying to play .90 and loving it so far! the only problem i have is that the blue research button doesn't show up when i select the basic rocketry tech. i tried to see if it was just my game and checked the science tutorial, but it wasn't there either. i deleted all local content and reloaded it fresh with no mods, and in career mode, science mode, and the science tutorial i am unable to see the blue research button, or research anything. i am running it off steam with a 64 bit windows 7, but running it in 32 bit mode. Any one else seen this or know of a fix? EDIT 1- tried another fresh install after deleting all file folders and still no luck. where the research button should be, it still says "Start Required". completely unmodded right now, so really not sure. the save file says; SCENARIO { name = ResearchAndDevelopment scene = 5, 6, 7, 8, 9 sci = 5 Tech { id = start state = Available part = mk1pod part = liquidEngine part = solidBooster part = fuelTankSmall part = trussPiece1x part = longAntenna part = parachuteSingle } Science { id = recovery@KerbinFlew title = Recovery of a vessel that survived a flight. dsc = 1 scv = 0.1666667 sbv = 5 sci = 5 cap = 6 } } so i think thats correct? not sure. any help is greatly appreciated!
