Played with this version for a bit (Windows 8.1, also updated Flash to 18.0.0.194), seems fine. Readme suggests the usual things which is updating everything (IE to 11, then Flash) and clearing the cache within KCV. You can also try to play in IE (since KCV uses it) and in Chrome (it has its own Flash included) and see if there is still a problem.

Do you use Windows 7? I can try it later (remember having some glitches on it).
