Sorry to hear you are having trouble,It looks like the file didn't upload fully.
Just tried to install it and it installs ok but it has no icon on the installer,maybe with the big installers you should split them up using winrar or put it in a rar or zip file then upload it.It will be easier to download it if you split the file up..
You can give Retofan the ftp user and pass if you like..
Oh let me reset my server first before you do anything..???
