Product manual missing

Question

I bought an EzCool MP34 Touch digital player and the disk it came with does not have a downloadable manual on it. The manual that comes in the box with the unit is poorly written and has no instructions on how to download videos to the player. There's an AVI converter program on the disk, but this has no help file! I've contacted the supplier, but they're dragging their feet and tell me they're not sure when/if they can send me the downloadable manual. This is really frustrating as I want to be able to start using the thing right now.
Can anyone please help me with this? Thanks.
