I'm trying to convert the "CRI HQ" mod from Fallout 3 to work with TTW, but whenever the .Esp file is enabled, my game ctds before my main menu even appears. Help.

Game always ctd before main menu when you have active esp with missing esm master.
Check what masters your esp should have.

How did you convert the mod? Maybe you messed up along the way.

Could be incompatibel with ttw

It's not incompatible, you just need the know-how of how to convert mods for TTW, that's why I ask, how did you convert them?

To save time, here's the proper conversion method:

Download the conversion script from the TTW site and FNVEdit, put the script somewhere you can easily find it. Go into FNVEdit, select the mod, assign all of the TTW masters and TTW as additional master files. Save. Reload the mod. Add the script. Select the mod, run the script (I believe it's right-click then run script).

That's what I did... I already said I converted it. I've been converting Fallout 3 mods the same way I always have for months. This is the first time something like this happened. Whenever I go into the GECK with CRI-HQ.esp enabled, my GECK crashes too. It's something in the mod, but I have no idea what, if it keeps crashing.
