the last file have safe only 1 item from so many item i do in file.

i dont know what to do with this .

Is Skyrim running while you have the Creation Kit open? If Skyrim is running, then you can't save the file. The new file you saved only contains new infomation, not the old file's information. Make sure Skyrim is closed and load up your original file and see if it will save.

and when you load an existing mod, you have to set it as the active plugin.

thank you you 2 so much .

now i can go on with my house.
