Game tells me my version of Skyrim SE is out-of-date. But it's 2.4(something).

Every time since I've installed the main SexLabs Frame, at startup the program tells me I have to have SSE of 1.9.7 or higher. According to the start screen, my version is apparently 2.40 (if memory serves. The seductions occur but there are no videos. A little help please?

Sexlab doesn't work with Skyrim SE. So that's certainly the source of your problem.
