Most likely, you installed FOSE with FOMM, and now you have a "fose_v1_2-beta2" folder in your root or data directory, instead of having the FOSE DLLS, and FOSE_Loader.exe in your Fallout 3 ROOT directory. You are correct, that is exactly what I did. Thank you for the help. I didn't think to look inside the .zip file before running it through FOMM...
