Newbie with startup problems

I have purchased and assembled a Aurora3D DIY RepRap Prusa I3 (Z-605) printer.
Almost all of my instructions are in Chinese as far as the drivers are concerned. I tried to install (stupidly) the chinese drivers and a bunch of junkware installed along with it - the drivers didn't work.
With no instruction manuals I don't even know if the printer is assembled correctly. I have 1 red LED on power up (next to jumpers at right side of board. The printer doesn't seem to do a POST startup sequence which seems strange but not knowing this printer.....
Anyway, I need drivers for this printer and some kind of instruction about how to tell if it is functioning. I have installed Repetier-Host V0,83 (recommended in docs with printer) but w/o drivers it just kind of looks pretty....
Help!
This printer has the Reprap Melzi V2.3 board.
I have searched all over the internet for any instructions to no avail. Can anyone lend a hand?
Thanks

I believe these are for an older version of Melzi, but it should get you started.

I was told by the vendor that I bought this from not to update the firmware....seems strange to me.

So it looks like the drivers are at least talking to WIndows. I have verified that the printer is connecting over COM5 and it has the FTDI verions 2.12.0.0.
When I try to connect to the printer within Repetier-Host (V0.83 - recommended by vendor) I get this error:
15:14:18.374 : Serial com errorystem.IO.Ports.SerialErrorReceivedEventArgs\
Any ideas?

Check connection speed. I have 250000, using Pronterface.

It sounds like the FTDI chip on the Melzi has been soft bricked by the latest FDTI drivers. That could explain why the vendor didn't want you to update it. FDTI released the 2.12.0 driver to purposely soft brick counterfeit/clone FDTI chips. The driver sets the PID to 0 which soft bricks it.

There is a pretty big uproar in the electronics community about it, so much so FDTI has backtracked and taken that driver down. You can search FDTI and brick and you'll see the story.

Damn straight its an uproar - blocking their drivers to not work is fair enough, but software bricking someone elses' gear is just straight vandalism. Most buyers wouldn't have a clue whether they have legit chips, nor do they have control over the buying process.
