Using java Aspose.Words.jdk15.jar, version 2.3.0.0

Any ideas what could cause this? We’re seeing the following exception when initializing the license:

Hi, David,

It’s seems that your license file is corrupted (or just edited by someone). Could you please attach your license file?

Best Regards,
