We had a situation where our license in production went bad on a server. This is on the reporting services side. We have a total license but our powerpoint reports would show the watermark as if the license had expired when in fact it had not. We had to copy the license from another server to resolve the issue.
The other question I have is regarding the version referenced in the watermark. It said 'Created with Aspose.Slides for Reporting Services 7.7.3.0." The version we have on the server is 4.9.0.0.
I’m not sure what other information would be useful but we’re simply trying to figure out how to prevent this in the future.
