Chinese Name to Structure

Hello.  I've been pulling patents off of google.com/patents and I came across this Exception using DocumentExtractor:

chemaxon.license.LicenseException: No valid license has been found.

Product name: Chinese Name to Structure

I double checked the patent and it is definitely not in Chinese.  It is a US patent.  This behavior would seem to be a bug.  Thanks.

There was indeed such a bug which was fixed in version 5.12.1. Are you using 5.12.0?

If not, could you mention which specific patents generates this behaviour?
