I'm afraid, such version of the V-Ray renderer isn't supported yet. The last V-Ray version supported is the V-Ray 3.5.xx (since the Forest Pack Lite/Pro 5.3.2). Currently supported V-Ray versions are 2.5, 3.1, 3.2, 3.3, 3.4 and 3.5. We usually publish versions with support of the latest V-Ray's version soon after such V-Ray release becomes officially available. Thanks for your comprehension.
