OK, if you unzipped directly to the modules folder, you still may have an extra folder due to the zip archive. Open that folder and see if you see a file named "xoops_version.php" if that file is seen when you open the folder you have the correct folder uploaded. If you see another folder and no xoops_version.php, then you have too many folders uploaded.
Just a note: It is easier to unzip on your local computer, find the right folder, then upload the proper folder to the server.
HTH.
I have other tutorials on my site on this subject, and others.
