The FTP client that you uploaded the files and folders that power Vshare should have been set to binary mode.
Probably the easiest way if you are new to this, is to download a copy of WSFTP lite, here's a link:
http://oldversion.com/program.php?n=wsftp
It uses standard navigation, but make sure that when transferring files that the radio button is set to binary.
Or, if you don't want to go through all that, read the help files with the ftp client you are using.
