JohnO I started using the free version of Photopad. I liked it and downloaded the pro Paid version. Do I have to start over or is their a way I can get rid of the watermarks. I only used the program for a couple of weeks but processed a lot of photos and do not look forward to starting again! JohnO
Fred28 Sorry it seems that any content created using the free version will always have the watermark and it cannot be removed by purchasing. You will need to start over or try and select cut and replace the part with the watermark. You can confirm this with NCH support: https://www.nch.com.au/support/index.html 
Lourod This wasn't the case with the previous version which I have been using on behalf of my Rotary club for a long time. If we can't remove the watermark, the product is useless to our community service organisation. Lourod
