I could not activate the license as it gives me an error: "Invalid Encoding for the Signature"

If you received this error, it is likely due to one of two reasons:

1) The trial key could have been copied to the license area instead of the Activation Code area highlighted in the picture. If so, simply paste the activation code and press Activate Automatically button. Once the license is retrieved press the Complete Activation button in the lower left.

2) If you are using Manual Activation, please make sure to include the ----------------LICENSE BEGIN---------------- and ---------------- LICENSE END ---------------- when pasting the activation key.
