Including Lightspark PPA int repositories error

I would like to use the latest version of Lightspark, so tried to put the ppa into my list of repositories. I got the following error message, which I don't understand:

sudo add-apt-repository ppa:sparkers/ppa
[sudo] password for yeehi:
Traceback (most recent call last):
File "/usr/bin/add-apt-repository", line 88, in
ppa_info = get_ppa_info_from_lp(user, ppa_name)
File "/usr/lib/python2.7/dist-packages/softwareproperties/ppa.py", line 80, in get_ppa_info_from_lp
curl.perform()
pycurl.error: (28, 'connect() timed out!')

Could somebody please help me?

Thank you!
