Free Cakewalk Sonar Activation Requirements

[Hotel California]

Hi, 

1. How often does activation need to activated on Free Version of Cakewalk Sonar, and is it through Cakewalk Sonar or Cakewalk Product Center?

2. Will it still work if Activation is not possible while using it where there is no online service like while at a live performance?

3. Can we use Free Cakewalk Sonar on 2 different computers?

Thank you and look forward your responses!
