Version I have is 7.1.4

See attached Image for Whole Screen.

You still have the stream part at right. See the attachment and put the cursor inside the green circle (but on your screen) and pull it to the left then you must see the stream window.

I now have a new problem.
When I click on the Activities TAB don't see the activities anymore.
I only see this response "No Activity selected."

But it shows a white Screen with only the menus.

that is because you pull it too much to the left

Found the activity stream. Thank you for that.

With the white screen showing that error message I can't seem to find where on the left side it is to pull it back to its original place.

See attached image

I worked it out.

I had to close the menu part on the far left to very small, which then showed the Activity Stream and I was able to pull it back to the right.

All fixed now.
