VCS Update Manager comes out and notifies that the entered registration information is not working.

The problem might occur due to following reasons:
- You mistyped the license information.
- Changes were made to your computer’s configuration or you are trying to transfer the software to another computer. That will lead to a change of Protection Number and cause invalid license error.
- To check if your Protection Number has changed, download this "vcs_protection_number.exe" file and open it to find the current Protection Number of your computer.
- For details about license resetting, please visit Customer Care Policy.
