I just got done making a house outside of Balmora. I saved it and it isn't showing up in my Data Files folder. In the Construction Set it shows up just fine under File->Data Files->. When I was working on the house it crashed, so when I reopened it and started working on it again (I forgot to put it as active file) I saved it as another file, Kitchen2. That isn't showing up either. Idk what's wrong. This like my 3rd time using the Construction Set, so I probably screwed up somewhere.
Thnx.
Is your Morrowind install folder is under Program Files? Windows prevents changes to Program Files folder, and sends those files to a compatibility folder.
C:\ProgramData\
I recommend installing somewhere else than program files.
Hint: You can copy your entire morrowind folder to c:\games\morrowind\ and it will work.
