Have you any sort of similar issue on the the mod page, or its comments?
If not you might want to try the following:
-Re-download/Re-install the mod
-Verify the game's cache integrity through steam
-Try another pipboy replacer and see if you encounter the same issue. http://www.nexusmods.com/fallout3/mods/16836/?
-Run the mod through F03 Edit to see if there could be a problem as well.
