Kaser Mambo Mano 4GB YoFun104 - I have spent already 12 hours on it

- still lost, very lost
i download it the manual and utitlity driver from the site . It is a zipped file. I opened it but do not known which is the driver. They are in my usb drive.
I connect the Kaser Mambo Mano 4 GB YoFun 104 MP4 player ( I thought is it Mp3, do not know what is MP4 and its difference), nohting happen on the little machine, just black. I drag some songs from my computer hard drive to the folder that I download, noting happen. I have no idea what the adapter is for. The case came apart as soon as I open it. I plug one end of a cable into it and hold the case with a rubber hand, it cannot fit easily. Nothing I notice was happening. No light. No nothing even after I hooked it at first to the gadget, think that it needs to be charged. How can get even one song into the player . I am so lost... [email protected]
