Has anyone ever had this problem and knows how to solve it?
I closed and saved my project and then when I went to open it disappeared many objects that were in the scene (They are not hidden)

(Another one of the reasons that I have been giving up keyshot is that out of nowhere it corrupts your projects ...)
What version of KeyShot are you running?
KeyShot 6
I've had this problem once, maybe twice, when I've done a lot of reordering, renaming, and regrouping of objects in the scene tree.
Right there was some issue like that in KeyShot 6. This has been completely resolved in KeyShot 7.
