Does anyone else have trouble opening some of the files from the Shoppe?

[scrap2day]

I'm hoping someone can help me. Sometimes I get files from the Shoppe that I can't open. For instance, I had no trouble opening Libby's Stone Age Family. But when I try to extract the files from Janet's 2 Many Photos 10 I get the message saying that I am trying to copy a file because there is already a file with that name but I can't really do anything to change it. I'm using Vista.

Does this happen to anyone else? How do I solve it?
