**Which product are you using?**

**PDF.js Express Version**

**Detailed description of issue**  
I cannot generate a license key for a .co.uk domain name as it says I don’t need to include subdomains but the root domain is actually [xxxx.co.uk](http://xxxx.co.uk) (it only accepts [co.uk](http://co.uk) as the domain but leaves a watermark on the PDF when I use that and test it).

**Expected behaviour**  
No watermark in the PDF viewer

**Does your issue happen with every document, or just one?**  
All documents

**Link to document**

**Code snippet**
