Error: Block key "variable_slider" not found

GNU Radio
1

Hey,

I am using the 3.7.2.1

on win7 64bit on a Lenovo i5
Gnuradio was installed from pre compiled bin
When it loads it display this :

Warning (from warnings module):
File
“C:\Python27\lib\site-packages\cheetah-2.4.4-py2.7.egg\Cheetah\Compiler.py”,
line 1509
"\nYou don’t have the C version
of NameMapper installed! "
UserWarning:
You don’t have the C version of NameMapper installed! I’m
disabling Cheetah’s useStackFrames option as it is painfully slow with
the
Python version of NameMapper. You should get a copy of Cheetah with the
compiled C version of NameMapper.

<<< Welcome to GNU Radio Companion 3.7.2.1

And then I open the dial_tone example to see if it’s
working o.k and I get:

Loading:
“C:\Python27\gnuradio\share\gnuradio\examples\audio\dial_tone.grc”

Error: Block key “variable_slider”

Done

Showing:

It’s not working + I can’t add blocks…I see them on the
side screen but when I double click them nothing happen.

Thank’s,
