does not play sexlab animations

[Gyurma1]

I can't figure out the error, I managed to install it a long time ago.

A long time indeed.

You should look into upgrading MO. Current version is 2.4.4.

I use XP32 Maximum Skeleton Extended.

Your XPMS looks too low in your priority order. It should be above (with a smaller priority number) than all your sexlab components.

Using LOOT should help fix load order issues, to a point.

I don't know that any of these will fix your problem, but they are worth a try.
