SuffolkWave

I found SuffolkWave a little tough to navigate, though I'm sure the computer savvy would have no trouble with it. Quickly glancing at the SW homepage, I was looking for underlined words to click on, so got into NetLibrary, then tried to find downloadable audio books but couldn't find them. It wasn't until I meandered back to the homepage that I realized I should have clicked on the big Suffolk Wave banner ( I always forget that you can click on them) that I found the audio books. I had no trouble downloading Overdrive Media, but tried twice to download books and couldn't. (Error:Ox80070057: the parameter is incorrect). It could be my home computer. ???
I think I'll move on to the next segment. One thing that I disliked about SuffolkWave was that many of the audiobooks didn't have copies available to download. Why is this and how can it be remedied? What's the point of having a catalog if very few are available? I'll stick to Books on CD and hard copies, thank you very much :-)
