You are more than welcome. Since you are using a lurker_hlb3 mod, it would be a good idea to "study" what he did, compared to the stock game, with his different files, especially the campaign files. You'll understand the folder structure and where to find everything after a little practice with it. Also, read his different ReadMe text and pdf files for more info. To help you along, here's the v17 ME manual that Dietrich did on behalf of 17. Unterseebootsflottile »Nordfront« (their site unfortunately is now defunct):

That is a 7zip file, with a folder inside of it that contains their Mission Editor manual. While it is for SH3, it almost applies fully for SH4, though you'll notice the Mission menu is different, with the Parameters in a separate section, as are other items. However, these guys paid attention to the details of the ME, and do a good job of getting you a leg-up on the knowledge. They do not speak directly about Campaign editing, and are more toward the Single Mission type of editing, but it applies to the Campaign also, and definitely helps a person grasp the concepts. They do not speak to using a text editor for helping edit "lurker style"...
