Well I have a policy of not installing any mods (I need my TTW as vanilla as possible for testing purposes) so I can't really help in here, but I checked the mod page and I can't see anything related to it needing FOSE so I recommend you check out Chucksteel's FO3 Mod conversion guide for TTW since it is easy to follow and teaches how to do it without any complications.
Check the end of the first post here for all you need to convert FO3 mods that don't require FOSE to work with TTW, if I am not mistaken you need the conversion pack and you just follow the instructions on Chuck's pdf Guide.
Good luck
and even if you do the conversion method and it doesn't work, then maybe ask for more help around, maybe someone more knowledgeable than me will check it out.
