Common questions

The phone says "Waiting for your PC". Check Screen Markup is open on the PC and that the code on its window matches the one the phone is showing.
The mouse does not respond. Make sure "Let the phone move and click my mouse" is ticked in Screen Markup. Windows does not allow one program to control another running as administrator; run Screen Markup as administrator too if you need that.
