Trouble shooting

(1) If you get error message like "Invalid user name or registration code...", please make sure again these info are correct:

(2) You are using correct edition you bought, maybe you bought Pro version, but you are using Ultimate version.

(3) Maybe you bought Star PDF Watermark (for pdf files), but you are using Star Watermark (for photos).

(4) The registration name is your payment email address.

(5) Typed less or more character in register name or code.

To avoid a register issue, the best approach is to download and install from the download link in your payment email inbox you received.
