You posted in the end user section - so I assumed you had the end user drivers.
I believe this is related to your code and how the watermark is called/used, but if you can provide a compilable sample project - that will be great.
Make sure that no license information is present in any such sample provided.
As for which versions you can use - I will be able to answer that if you send me your order number or license key to firstname.lastname@example.org
with a link back to this topic.
