It sounds like your back up may be corrupted also.
Here is something to try.
Make a copy of you module from a month ago. I Will call it "NewMod.mod"
Change the file extention on the back up module to .erf
Open the NewMod.mod in the toolset and inport the .erf (BackUp) into it.
.....
You can also try opening the BackUp module with the HakPack editor, extracting the .ifo file and opening it(the .ifo file) with the .gff editor to see what haks are listed.
......
EDIT: Just for refferance. .mod .sav .hak and .erf are all the same file structure. They are just a bunch of little files all stuck together into one big file. you can compair them to a .zip or other archive without compression.
