Building and Publishing problems

I’ve built one of my games for Unity WebPlayer. Now, when I try to update it by building it again, it builds the earlier version (source code keeps the same). I don’t know how is that even possible and why is that happening.

If you got what I meant, and know how to fix this, please answer.

You might be simply running the old compile.

1- create a new folder on your disk, for example c:

ewcompile
2- click the FILE menu and then BUILD SETTINGS
3- click the BUILD button, and go to your c:
ewcompile folder
4- choose a name for your new build

Your freshly built project should be now correctly available.
