CUBASE AI 4 COPY AND PLACE ISSUES!?!?

I have cubase AI 4, when i record my hooks and then try to copy and paste my hooks where they should be on the song, it does not let me place them exactly where they should be to match with the music how the original hook does and sounded. On my older version of cubase i didn’t have this problem i could record copy, paste, and drag the hook right where it should be to match! CAN ANYBODY PLASE HELP ME !?!?
