anyone have any ideas

im currently building a prusa, I have ramps connected to a via epia-nl running windows xp, all mounted on the prusa frame, connected with the same power supply.
I have use the ide to installed teacup on the mega2560.

I have tried sevreal diffrent programs, none have worked

replicatorG - can connect, knows that is it is connected, Cant seem to do anything.
Printrun- only one that does anything at all(it can turn the extrueder heat on, thats it, no temp feed back)
Repsnaper - just dispays werid lines at a 45/ on screen

Not sure about teacup, but you could trye Sprinter and Pronterface or Repetier
