What Vent said will be the issue.
Every time you test a level in FPSC it creates a bunch of DBO and BIN files, (so it loads faster next time) all of the data needed for models and textures in that level are stored inside these DBO and BIN files.
If you altered a model and then placed it back where you found it with the original DBO file, there won't be any change.
I would advise, delete the DBO file you placed back in the folder, run FPSC cleaner, then try to text it again.
If that fails, then, as D13 mentioned, learn to use a modeling program to edit models rather than using DBO (its easier once you learn the basics and very fun)
Hope this helps.
