I found that if I needed to move an anchor point, I click on the Convert Anchor Point Tool (Shift + C on a PC) and PRESS on the point I want to move while I hold down the SPACE bar.
This will make your line look like rubber bands that are stretched out from on point to the next,then I would simply double click on the anchor using the Convert Anchor Point Tool, and bend the line with the handles.
Hope this helps someone.
