I had the same problem and what I found was >I re-installed the 3.1.7, but issue/problem was still there, so I checked my DLL in the vst pugin folder and the DLL was a different version than the 3.1.7 install, so I replaced the DLL in the vst plugin folder with the new 3.1.7 DLL ( Problem Solved and it works great ).
