Deleting any registry entries that may have been left over from the installation would help. I don't know what the specific keys are, but doing a search for "fallout," "fomm," or anything similar in regedit should help. Also try deleting any recent Windows restore points, error logs, and/or old prefetch data. Also make sure that the FOMM folder and everything in it was removed when you uninstalled it.
It's not a solution, but consider using BAIN in Wrye Flash instead. I understand if you have converted all your mods to FOMOD packages that you'd want to stick with FOMM, though.
