Im running version 1.6.0 Beta 2.4 and when i open a browser i get nothing, Just the K-melon page with nothing atop the page for searching or anything. Attached is (hopefully) a working link with the picture of what im seeing.
Also it can be broken download - your had reported not only one problem so I guess you have not all files unpacked successfully from the dpwnloaded package.
Try to redownload and reunpack KM. Another option is to download latest KM Twin which is based on KM 1.6 beta 2.5 by JamesD.
