Yes I did try what you suggested filosofem but to no avail. This does work with non-encryped content such as samples that you sample yourself but not with factory content of structure which is at this stage all I have. The folder which these are contained in is: Programfiles/digidesign/structure factory libraries/structure encryped samples/samples DVD 1 (etc) When you try replacing any sample with anything on this folder, you will find that there are no samples or wave files in this folder only "big files" whatever that is, thus you canot import them. My theory is that structure patches have been protected for God knows what reason. I take it you dont have problems with replacing samples. This to me impies that either 1. you have never replaced samples, 2. you have not replaced factory content or 3.you have and been successful and Im doing something wrong, perhaps looking in the wrong location.
