Just wanted to add something to this thread. I have been trying to login all day, trying various mods and settings suggested, reinstalling, re-uplaoding, etc.. I finally tried uploading with a different ftp client and the install worked flawless after that, logged in first try. I am on a Mac and was using RBrowser for ftp, when I switched to Fetch , no problems. I know this won't fix everyones problem, but it is worth a try for those of you that can't seem to get it working.
