I'll start out by letting you know that I use several other image editing programs and am not that familiar with Paint Shop Pro.
That said, there are still basic functions and similarities that most photo editors share.
Further, just like film, there are limits to what can be done to recover from exposure errors on digital images.
If an area of the image is severely washed out from too much light, or nearly dark from too little light, you cannot recover a "normal" looking image from that area of the photo.
Start by opening the raw image and saving it as a .BMP or .TIF file.
Do NOT convert back to a jpg or other compressed format until you have completed ALL editing.
(you lose some image detail each time you save a jpeg file)
Use your brightness and contrast tools to adjust the overall image for the best compromise exposure.
Use the selection tools to select areas that are now either too light or too dark and adjust the brightness and contrast of each area as needed.
(this is similar to the old photo enlarger technique of dodging and burning)
Take your time, and save often.
You might even rename the file every few saves so that you can easily go back to a previous edit.
Newer version of Paint Shop Pro, and Adobe Photoshop Elements have improved algorithms in the automated tools and will be able to do a better job of fixing the exposure error.
Another option would be to find a graphic artist who specializes in image editing.
