With so many modders offering their mods as ESM's I need the ability to open and edit the ESM in order to tweak things or just to see what they are doing. However, I cannot figure out how to open an ESM in GECK. The only indications I have found is that they need to be converted to pluggins. I have attempted this using Wrye and also using TES4Gecko. Nevertheless, the GECK freezes and crashes when attempting to open an ESM that has been converted to ESP. No combination of opening dependent masters first seems to work. Could someone point me to a tutorial or give me some pointers on how to do this. I will post this question in the GECK FO3 forum as well.

Am grateful for any help.

Use NVEdit.
