XEO 5 and XEORC4

[Lastito]

alright, here's the problem, I'm trying to open a save file XEO chocolate elf

so I download the XEO5obse

and then somehow the save file won't show the char

after I check it with Oblivion Face Exchange Lite, it appears that save file needs xeorace.esm

which is on my XEO5obse is xeoex.esm

so my question is, is I have to download the XEO4 or I should change that xeoex.esm to xeorace.esm?

thanks for read-n-reply :D
