Fallout3.esm Corrupt?

[mastertrain]

I am on Windows 8.1, have 4GB of RAM, and use an AMD A8-4500M APU processor with 1.90 GHz. I mostly use Nexus Mod Manager 0.53.2. I installed TTW long ago, and have since lost the install log. My Load Order is attached. Every time I launch FalloutNV, it freezes on the first screen that shows up. I have check in NMM the list of mods, and when I click on Fallout3.esm, it shows on the right side of NMM "Warning: Plugin appears corrupt." I have tried disabling all mods, except TTW, FNV + DLC, and F3 + DLC. I also thought I should say that I don't remember which version of TTW I installed, as it was a long time ago. If I was able to find a Fallout3.esm post-TTW, and replaced mine, would that possibly fix the issue?

 

Just thought I should note, all these mods have worked, and have ran well together in the past together.

Sorry that I forgot, but Fallout 3 is Steam Download

I'm hoping what you mean to say here is "If I download the new installer and run it, would that possibly fix the issue"

Using your FO3 esm will break your game, and anything else is probably illegal.

I took him to mean if he found an old fallout3.esm on his hard drive somewhere, would it work. But maybe 

I am just naive.
