NCH has the trial and the free version, they are different. The trial version is the full version but it will expire after a few days. Based on what you stated, it sound like you have the trial. The free version does not expire but will only burn CDs, it will not burn DVD nor Blu-ray discs. If you need to burn DVDs, you will have to purchase a license. Otherwise, you can uninstall your current version and reinstall the free one here: https://www.nch.com.au/burn/burnsetup.exe
