Your link doesn't lead to what I think you think it leads to.

yes they have just removed it .. claiming that it wasn't a file .. i was a bit to late to upload it in a .txt. form
basically what you have to do is :
unpack the and FO3 bsa meshes ...
start fomm
go to tools - bsa unpacker and open the meshes.bsa located in fallout3\data folder
inside fomm navigate to characters/_male and extract the locomotion folder
delete the hurt and children folders inside and copy it to fallout new vegas/data/characters/_male folders
that's it
to uninstall .. just remove
oh and don't install anims from Fo3 or mods for FO3 .. that have attack or IS in their name ... like 1hpaimIS
