I've been using Adobe Acrobat X Pro in Windows 10 for 2 years now and this is the first time I have encountered this kind of bug/error.

First problem was Acrobat crashed then I can't open it anymore so I re-installed the whole CS6 Design and Web Premium. Afterwards, that's where I saw the texts were highlighted in different colors. If I zoom in, the highlight disappear but when I zoom out, the highlight changes.

Can someone help me?
