FOMM crash

(Posted this on nexus but I assumed later on that it might be better to post it here)

Starting today whenever I try and run FOMM for Fallout 3 it says "FOMM needs to upgrade some of it's files. This could take a few minutes depending on how many mods are installed"
So I click ok which is when this happens: "An error occurred while upgrading your log file. As long as it wasn't too bad, a crash dump will have been saved"

Crash dump:

"Fomm 0.14.11.12
