I have a serious problem after I reinstalled cubase 5. Pls help me !

Hello, this is Lewis Park from South Korea.

Because of a problem in WINDOW 10 Pro, I reinstalled windows, which means I reinstalled Cubase 5 and Waves plugins.

So the problem is everywhere I stop playing in cubase project, there’s something ghost sound lasting.

What I mean by that is there’s some sound which is lasting and repeating the very previous sound before I stop playing.

I already reinstalled again the cubase and waves plugins, but the problem wasn’t solved.

Anybody who’s got a solution to this ?

Thank you.
