[SOLVED] ppython.exe has stopped working

I just installed Panda3D 1.8.1 on my Windows 8 x64 install and whenever I try and run ANY script, the following happens:
-The window opens and stays black momentarily
-then it proceeds to crash, no warning, and just says ppython.exe has stopped working

I’ve tried with this basic script from the manual:

from direct.showbase.ShowBase import ShowBase
 
class MyApp(ShowBase):
 
    def __init__(self):
        ShowBase.__init__(self)
 
app = MyApp()
app.run()

as well as a much longer script that I wrote derived from the Manual Hello World tutorial:

from math import pi, sin, cos
import socket
import sys
import time

from direct.showbase.ShowBase import ShowBase
from direct.task import Task
from direct.actor.Actor import Actor

class MyApp(ShowBase):
	
	def __init__(self):
		ShowBase.__init__(self)
		
		# Create a TCP/IP socket
		self.sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
		# Connect the socket to the port where the server is listening
		self.server_address = ('192.168.0.10', 10000)
		print >>sys.stderr, 'connecting'
		self.sock.connect(self.server_address)
		
		#Load the environment model
		self.environ = self.loader.loadModel("models/environment")
		#Reparent the model to render
		self.environ.reparentTo(self.render)
		#Apply scale and position transforms on the model.
		self.environ.setScale(0.25, 0.25, 0.25)
		self.environ.setPos(-8, 42, 0)
		
		# Add the spinCameraTask procedure to the task manager.
		self.taskMgr.add(self.spinCameraTask, "SpinCameraTask")
		# Add pandaHand to task manager
		self.taskMgr.add(self.pandaHand, "PandaHand")
		
		# Load and transform the panda actor
		self.pandaActor = Actor("models/panda-model", {"walk": "models/panda-walk4"})
		self.pandaActor.setScale(0.005, 0.005, 0.005)
		self.pandaActor.reparentTo(self.render)
		# Loop its animation
		self.pandaActor.loop("walk")
	
	# pandaHand
	def pandaHand(self, task):
		
		#Receive data from RasPi
		ADC_list_elements = 5
		data = self.sock.recv((ADC_list_elements*5)-1)
		print >>sys.stderr, data
		#Transform data string into lof
		# IR   , FSR  ,     -,     -,     -,     SW3  , SW2  , SW1
		#  0       1      2     3       4          5     6       7
		y = [float(datum) for datum in data.split(',')]
		#Set panda height equivalent to IR voltage
		self.pandaActor.setPos(0,0,3.4-y[0])
		#Set panda scale relative to FSR
		self.pandaActor.setScale(0.005, 0.006-(0.001*y[1]), 0.005)
		#Set orientation depending on button values (either 0.0 or 30.0*~4.96)
		self.pandaActor.setHpr(180 if y[4]>4.0 else 0, 180 if y[3]>4.0 else 0, 180 if y[2]>4.0 else 0)
		
		return Task.cont
		
	
	# Define a procedure to move the camera	
	def spinCameraTask(self, task):
		angleDegrees = task.time * 6.0;
		angleRadians = angleDegrees * (pi/180.0)
		self.camera.setPos(20*sin(angleRadians), -20.0*cos(angleRadians), 3)
		self.camera.setHpr(angleDegrees, 0, 0)
		return Task.cont
		
app = MyApp()
app.run()

Both of these work fine on my Ubuntu 12.10 x86 install but Panda3D just seems to catastrophically fail everytime I try and run it on Windows. Any good way of debugging this?

Are your video card drivers updated to the most recent version?

I was on Catalyst 13.3, and I just upgraded to Catalyst 13.4 (which was only release like 3 days ago).

Problem is now fixed… thanks. :smiley:
