The font is too small, it is hard to see.
How to enlarge the font in the writting place?

I installed Miktex 2.7
GS 8.64
Gs view 4.9
Adobe reader 9(for pdf)
but the TexNicCenter does not work


I got 2 error messages

1 form pdf reader: There was an error opening the document.

2 from TexNicCneter:
Docopen("%bm.pdf") ["Fileopenbm.pdf” ], can not execute the command.

How to slove ...
