Hi Support Team,

we have UltimateDocument Expert for .NET licence.
We have developed an application hosted on IIS which allows us using WCF generate multiple types of documents, most often DOCX and PDF.
From time to time we face a strange problem. One of the WCF calls works fine until an error "Your license key for ComponentPro.Word is expired or used for an older version." occurs.
Then, the call fails until IIS application pool is recycled. Then it works for a while and the whole thing repeats itself. Other calles still works.

It looks like the error in this article

Any idea what is the cause of the problem and how to resolve it? Thanks in advance.


Note: This question has been asked on the Q&A forum of Thang Dang's fraudulent ComponentPro brand
If you purchased anything from ComponentPro, you have been scammed. Contact the payment processor
who sold you the license and ask for your money back.
