I had that problem. Its when you arent aligning it correctly. No offense, it happened to me as well.

1. Put it on a flat surface and look straight down on the screen.
2. Lightly tap dead center of the cross and hold. i use a toothpick to align. Hold until it changes to a new location. Do NOT press hard, it is not needed.

Thats the best way to do it.
