Is it in the right format? Just a thought. Have you tried downloading it in another format? I'm sure another Cutie will have a better answer for you. Sending you this answer to move you back to the top. Good luck!

What operating system do you have? Vista and Windows 7 allows you to click on the file and pull out the file without unzipping. Or you can right click on the zipped file and select extract

I know the feeling. Last weekend I decided to start doing a sort and toss of all my downloads and files-was doing great, tried to get back into it Sunday morning and for some darned reason-I couldn't do anything either-I must have accidentally "threw out" my extraction program or something. I don't "do" computers so today I am taking it to my computer go to guy to see what dumb thing I did or didn't do and get things back to working order. Hope you have gotten yours sorted out since you posted this-and crossing my fingers that by later this afternoon mine will be too,
