問題1：免費試用版有哪些限制？
我們網站上的所有軟體均可免費下載。您可以先下載免費試用版，充分評估後再決定是否要購買完整版。
Video Downloader only allows you to download 10 UHD full videos in 2K, 4K, and 8K. You can try this software for free within 15 days. When the 15-day free trial period ends, you will need to purchase the full version to continue using it.
Q2：我需要多久才能收到啟動碼？
通常情況下，啟動碼會在付款後立即自動發送到您購買時使用的郵箱。如果您在郵箱中找不到啟動碼，請檢查您的垃圾郵件資料夾。如果您在 24 小時內仍未收到啟動碼，請透過以下方式與我們聯絡： support@ios-unlocker.com 我們會盡快回覆您。
Q3：如何啟動軟體？
First, you need to download, install and run Video Downloader on your Mac/Windows computer.
然後，在軟體上輸入您的電子郵件地址和啟動碼以啟動您的帳戶。
如果您在啟動軟體過程中遇到任何問題，請隨時聯絡我們的支援團隊。（mailto: support@ios-unlocker.com）.
Q4：為什麼我輸入的許可證金鑰無效？
If the software shows that the license key that you entered is invalid, you might have purchased the wrong version of Video Downloader. For example, if you're using a Mac but accidentally purchased the Windows version, the activation will fail. If you have purchased the wrong version, please contact support@ios-unlocker.com ，我們會協助處理您的疑問。
Q5: How many videos can I download at once?
There is no limit to the number of downloads. You can batch download all the videos you want at the same time.
Q6: Why do I fail to download the video?
If you fail to download a video, it may be that the product does not currently support the site. Please check the supported websites on our official page. What's more, please make sure that you can watch that video on the website.
If you still can not download the video, please contact us via support@ios-unlocker.com.
