Can't open kjams

[carmar]

I'm a new user to kjams and I've downloaded kjams for windows and also lame and quicktime. When I try to open kjams I get the mesage
"The Compressed (zipped) Folder 'C:\User\use\Documents\kJamsProWin.zip' is invalid."
Help, I don't know how to open kjams
I use windows 7

you probably need to let the download finish. re-download it.
