Hi, people. It’s unethical, I know, yet, since I’m seriously cash-tied!

I got a free trial download of a ecover creator software (ebook covers). It is fully-functional, but in the images that it creates, SAMPLE is stamped as a watermark.
I can’t do anything. Could you please tell me a way of removing it - other than buying the registration code?
I’d be really delighted if you do!
