Did you try to purchase Aspose.Slides?
Please send me email or private message with order details.

Hi, did you get any solution to this problem? Excactly the same problem occurred on my computer today. Error message “the evaluation watermark has been changed”.

Are you sure this exception was thrown by Aspose.Slides? Could you provide stack trace please.
The most interesting, Aspose.Slides doesn’t contain such exception and even such text string inside assembly.

I got the "watermark" message from Aspose.License. I know you don't provide support for this component, but I would be happy to know if you have any solution/tips/tricks to it.

Jo.

I’m afraid I can’t help with this problem because I didn’t even see
Aspose.License and don’t have any ideas how to work with it.
