Today I tried installing KerbalEDU on several of our computers. One of these had a previous version of regular KSP on it. KerbalEDU works 100% on all the computers but the one who had a previous version. On this computer, I could see the KerbalEDU parts and scenarios but the special functions of these parts were not working (ie: the force indicator was only displaying a static arrow like it does in VAB instead of dynamically changing arrows as a function of forces being applied to ship). I figured there might be a conflict with previous KSP files so I deleted everything KSP related on the computer and tried installing again. Getting the same problem. Any ideas?
