Sounds like a worksheet protection issue - check that the worksheet where the
paste button is disabled is not protected.

Even I checked the box under tools/edit/show paste button, I can not copy and
paste from one excel workbook or file to another.

How can I make the paste function work again? When I am in a work book, or
click on Edit, the "paste" option is not highlighted on the toolbar.
