Revert to previous version of Dreamweaver from 2017.5

I just updated Dreamweaver to version 17.5 Build 9878. It is impossibly slow to refresh or to move between Design and Live views. In addition, issues that I and others have raised (such as the cursor not centering on the page but appearing at the bottom) have not been changed. Can I revert to the previous version? If not, I'm abandoning this product.
