Error while trying to apply Aspose.Word for Java license

We had just purchased for Aspose.Words for Java. Then I tried to test the license file but I got the error message below.
Here is the snippet java code, I am using for test the license file.

License license = new License();
File f = new File("D:\\Softwares\\Aspose Trial 11.7 .Words.Java\\purchased_license\\Aspose.Words.lic"); 
license.setLicense(new FileInputStream(f)); // ---> The exception was thrown from this line.
[Fatal Error] :1:1: Content is not allowed in prolog.
org.xml.sax.SAXParseException: Content is not allowed in prolog.

What could be the problem?
Now I am using Aspose.Words for java version 11.7.

Hi Smith,

Thanks for sharing your license file via email.

I have checked your license file, it is a corrupted file which does not have anything documented in it. So, when you try to set this license file in your code, you got this error. For your information, the valid license file is a plain XML file that contains details, such as the product name, number of developers it is licensed to, subscription expiry date etc. Either you did not download it correctly or you did not receive it fine.

Please post a query at Aspose.Purchase forum below:
https://forum.aspose.com/c/purchase/6 and demand a valid license file. one of our sales staff member will help you soon.

Hi Awais,
Thanks for your investigation. I 've asked purchaser to send me the license file again this time I could see the xml content of the file. Now I can use the license file in my code without any problem.
Thanks for your supports.
