[@Pam] Hey Pam — sorry to hear about the paste issue. If you got v1.0.52 from the SharewareOnSale giveaway, I’d recommend downloading the latest version (v1.0.55) directly from grabtube.org — it has several improvements and fixes.
For pasting URLs, you can either use Ctrl+V directly in the URL input field, or click the clipboard icon next to the box. If the clipboard button doesn’t respond, it’s usually a Windows clipboard permission issue — just use Ctrl+V instead and it should work fine. Make sure you’re copying the full URL (right-click the video → Copy link address) rather than just the page title.
