I get a free viewer license key in this domain(themebucket net) but still showing the **[pdfjs.express](http://pdfjs.express)** watermark. Why it happened?

I am also facing the same problem. I have license and it was working earlier, suddenly it started showing watermarks. Let me know how to remove it?.

Hi there,

You are using a free license key with the plus version of the SDK. Make sure you are using [the viewer package](https://www.npmjs.com/package/@pdftron/pdfjs-express-viewer) and not the [plus package](https://www.npmjs.com/package/@pdftron/pdfjs-express).

Thanks!  
Logan

Hello there @Logan ,  
I use the viewer SDK and created an profile with free license key, then added it to WebViewer constructor but in my console it says

> [PDFJS.express](http://PDFJS.express): A valid license key is required to use the view only build of PDF.js Express.

 ![image](https://canada1.discourse-cdn.com/flex031/uploads/pdfjscommunity/original/1X/cf8f531079348ecd28de4a35b1f54aa64e204628.png)  
and here is the WebViewer constructor

```javascript
WebViewer({
        licenseKey: 'added key here',
        path: 'path/to/js/PDFJSExpress/lib', // path to the PDF.js Express'lib' folder on your server
        initialDoc: 'some url here',
      }, document.getElementById('viewer'))

```

and I followed the instructions in Manuall Integration.

thanks,  
Kingie
