Ok so i did a complete fresh install. Same issue. The Engineer Redux parts work fine, infact this time I didnt even need to purchase them manually. However there is now a slightly different problem, Under the Start node there is now 3 LV-T30 engines listed as well as my modified one. I took some screen shots for you guys to see. Before purchasing. and after I purchased it, says owned. In the VAB, still greyed out.
