Answer 1

Looks like the properties of the UI Component on which you recorded has changed and so it is not able to perform your recorded actions. Verify if the search properties of the component is still the same as when you recorded.

Answer 2

Please look at the line shown below in your stack trace:

Microsoft.VisualStudio.TestTools.UITesting.Mouse.
Click(UITestControl control, Point relativeCoordinate)

This means that the CodedUI is trying to click on a control using a specific point on the screen. For some reason it is unable to find the control it wants to click. Maybe no button exists on this specific point. Most probably, the screen resolution of your current display device is different from the screen resolution of the display device you used to record these tests.
