Wrong hdt.dll extension for SoS

[SkeletonGunn]

That message appeared in when Floppy SoS loaded. Also I have absolutely no idea where to get RCAE (if I even need it) the link is dead.

I think that message relates to using either the base .dll that is in the HDT-PE mod, or any other than the one in FloppySOS. If you are using MO, make sure FloppySOS is loaded after HDT-PE, and that the HDTPhysicsExtensions.dll being used is the one in the FloppySOS mod - i.e nothing is overwriting the file in that mod. 

 

As for RCAE(Register Custom Animation Events), try this link - http://www.loverslab.com/files/file/2254-skse-register-custom-animation-events/
