Hi,
Sincere apologies for the late response for this post. If you are not getting a response (such as days have gone by) then please open a support ticket as we may have overlooked this,

The dll libraries have to be in a directory on the java.library.path property. Usually adding them to a directory on the system PATH variable will work, but you will need to double check that the directory is on the java.library.path in SoapUI Pro by going to Help -> System Properties and checking the java.library.path property.
