final cut X disappeared in my computer

I've just received a new macbook pro. I had final cut studio in my old mac but made the mistake of not migrating it. I thought that installing final cut studio would be better. Well, I couldn't install fc 7 because I needed to first install fc 6 and fc6 won't install in lion. I read here in creative cow that all I needed to do was to install rosetta from a snow leopard disk. I installed rosetta and then install the first disc of final cut studio2. The installation happened too fast and I knew that something was wrong.

I had final cut X in the new mac and now, after rosetta and an attempt to install final cut studio, i can't open or even see final cut X anymore. It says that I can't open it because the application is incomplete or damaged. I can't even find it in applications so I could delete it and go through the hassle of contacting Apple to ask for a new download of final cut X ( It was my second download).

Apple is closed and now I need to work but don't have final cut studio and final cut X won't do for what I need to do ( print out to tape ). What went wrong?
