Adobe Acrobat is the program to make a pdf-file. It's not free.
Adobe Reader is the program to read them. That's free and can be downloaded from www.acrobat.com. But you state you have it already.

The link between your problem (not being able to read some 'electronic e-mail statements' and some websites) and pdf-files is weak, at most, without more info.

And the problem with wordpad ("can't read wordpad" and "after copy and paste i've a blank screen in wordpad") is ununderstandable to me. What do you copy and paste?

You might consider to provide more information.
