Layers > Import from file. Alternatively, add a new layer and copy + paste into the new layer. In both cases, make sure the new layer is below the existing one (you can drag it or use the Down arrow at the foot of the Layers window).

You wish to replace existing text? An example image would help us.

Failing memory module?

I suspect you've downloaded something else (some of the Ads can be quite misleading). Download it from here and you should be sweet: https://www.dotpdn.com/downloads/pdn.html

Advancedish Planet by Mr Bobert has 113 images. I don't consider that excessive. Beginners should be led by the hand with small steps showing a screenshot.

I've updated the ZIP in the first post.

Create your chart in Excel. Select the chart and copy & paste into paint.net. The results are beautiful. If you're not confident creating the data lines, leave them off and manually add them to the chart once you have it in paint.net.

You're using the plugins versioned for an old version of paint.net. Download and install Ed's plugin pack for paint.net 4+. There is a zip linked in the first post in this thread.

Welcome to the forum Editing operations in paint.net are restricted to the active layer. This means the Recolor tool cannot operate on any layer except the active one. I suspect what you're seeing is actually the result of a blend mode in one of the other layers. As you recolor, the blend mode is reacting with the recolored pixels to produce unanticipated results. You mentioned that only one layer was affected. Check that layers properties and see if the blend mode is set to something which might cause this.
