Trapdoorspyder

Update: it may have something to do with my 6-year-old computer, but I'm not sure, so I'm still hoping for advice.

Hello. I was trying to get recorded audio segments from my Casio wk-200 (I don't think the model is relevent for this) to my computer, to be specific Audacity. Looking through the users manual, I found the place to download the appropriate data manager and did so. However, every time I try to run the program I get a abnormal termination error. How come I am having this problem, and how do I fix it?
