Can't send model to layout

[Elpiapo]

After I make a model I can't send to layout. When I hit "send to layout" a window pops up that reads "license limit exceeded". I add my license and the window reads license exists...no kidding Sherlock! I can open Layout and import file but when I reopen the file is "missing". I can relink file file but after I close it and reopen its unlinked. What the hell? I suspect I have the free version and the paid version in my computer but when I try and export to layout it opens in the free version but in the evaluation version. How do I fix this please?!
Thanks...
