Can't load product license into soapUI Pro running on Linux

We just purchased several soapUI Pro licenses which we want to use  few  on linux operating systems running soapUI Pro. When we tried to load the license the following occurs. We are able to load one of the licenses into soapUI Pro running on windows without a problem.
