The Problem is solved. But for everyone, who wants to know what I did, here are my steps.:smartass:
1: Go to the ME and take a look in the payload editor, how the weapon/container/... you want to replace is called. Then keep in mind, which aircraft you chose and which pylon you used.
2: Open the Scripts\Database\Names.lua and search for the name. You may have to replace the spaces with "-" or "_". If you found it, you also got the CLSID. Now you can check, if the CLSID is also used the the Aircraft's lua at Scripts\Database\planes\. If not, you got the wrong one.
3: Now you have to open a file in the Bazar folder. It depends on what you are going to replace. For bombs take the BombTable.sht, for missiles the MissileTable.sht and for other the ContainerTable.sht.
Now you can search for the exact name you found in the Names.lua and there you will find the name of the file for the .lom/.cmd file.
I recommend to use Notepad++, you have a lot of search functions (search a term in every file (you can filter) in a folder.) and the files can be viewed much better than in the M$ Editor. Here you can download Notepad++ http://notepad-plus-plus.org/ (freeware):thumbup:
