• Nag window which prompts that this version of File Downloader™ is unregistered. It appears every time you begin the download process.
• It will expire in a certain period.

Note, there is no need to re-download File Downloader™ after the purchase. Just use the license key as described in the documentation. It will work as a full version unless you try to use it with a domain or IP address you did not purchase a license for.
