Error running KivyCatalog example

[David Aldrich]

Hi

I am new to Kivy. I would like to run the KivyCatalog example but I get a runtime error.

This is what I did:

Installed Kivy-1.9.0-py3.4-win32-x64 on Windows 8.1 in:

c:\Kivy-1.9.0-py3.4-win32-x64

Ran cmd prompt and executed kivy-3.4.bat.

Created folder: c:\kivy\KivyCatalog

Pasted code from http://kivy.org/docs/examples/gen__demo__kivycatalog__main__py.html to KivyCatalog

Created c:\kivy\kivycatalog\container_kvs

cd c:\kivy\KivyCatalog

python main.py

C:\kivy\KivyCatalog>python main.py

libpng warning: iCCP: known incorrect sRGB profile

     raise FactoryException('Unknown class <%s>' % name)

 kivy.factory.FactoryException: Unknown class <PlaygroundContainer>

How can I fix this error please?

Best regards
