Why I can't write a comment on a PDF document?

[kary_rs]

Greetings,

     I downloaded Adobe Acrobat Reader DC for my computer; Toshiba Satellite with Windows 10, hoping I could edit my pdf documents (highlight and write comments). I can Highlight but when I went to write a comment it didn't showed any typing. I tried different ways to write the comment but none worked. The note did appeared but when I typed it didn't showed any letters and the cursor didn't move. I wanted to know how it could be fixed.
