We purchase a license for the Aspose.Slides and for some reason this below happens:
We installed the newest 4.0 version but we still had the watermarks in the downloads.
After installing the purchased 3.8 version at exactly the same position as the previously installed 4.0 version the watermarks disappeared. For us it looks like the license key is somehow valid only for the purchased 3.8 version.
We as well purchased the maintenance until next year.
Any ideas? could you help us asap?
