Error Code 19: V2C file is invalid - Required XML tags not found

When downloading Sentinel LDK license files (.V2C files), it is possible your email filters will strip necessary information out of the file. To confirm if this has happened, open your .V2C file in notepad to see if any text data exists. If there is no data, your email has filtered out the required information from your license file.

To fix this, you will need to remove the email filter temporarily that prevents you from downloading XML data and try to download the file again, or have us send your v2c file to a different email address that will allow you to download files that contain XML data.
