Cannot load GUI PiCar A

Hi we have built the Pi Car A, and when we try to start the GUI using client.py we get the following error message :

Traceback (most recent call last):
  File "C:\Users\Andy\client\client.py", line 652, in <module>
    loop()                   # Load GUI
  File "C:\Users\Andy\client\client.py", line 239, in loop
    logo =tk.PhotoImage(file = 'logo.png')         #Define the picture of logo,but only supports '.png' and '.gif'
  File "C:\Python27\lib\lib-tk\Tkinter.py", line 3366, in __init__
    Image.__init__(self, 'photo', name, cnf, master, **kw)
  File "C:\Python27\lib\lib-tk\Tkinter.py", line 3320, in __init__
    self.tk.call(('image', 'create', imgtype, name,) + options)
_tkinter.TclError: couldn't recognize data in image file "logo.png"

Please help ????

Open the file client.py with Notepad or other IDE, manually comment line 239, 240 and 241 (input # ahead of the line to comment out).

That has got the GUI and the video to work, so thankyou. The problem now is the motors run in the wrong direction. I have tried putting a negative valve into the GUI pressing the Motor A button above it and then restarting the server on the car. But the values don't change and the motor still runs backwards.

How do I upload new parameters to the car ?

Hello mate, same with my PiCar, I had previously bought a raspberry pi based car before, while it took some effort assembling that product, it functioned as expected. I bought picar-4wd expecting an easier installation, however when I received the product first it had a part broken and missing, I returned the product and was promptly provided a replacement. I Cannot load GUI, there's also an error appearing. Anyways, I hope you could help us with this matter, has anyone here have tried download game multiplayer football games? I can't download it, maybe there's something wrong with my internet.
