[ubuntu-uk] Everpad not launching Ubuntu 13.10

[Gordon Burgess-Parker]

I installed Everpad to connect to my Evernote account and yesterday I
noticed that it wasn't in the indicator panel.
I tried to launch it from Unity Dash, but nothing happened.
I uninstalled and re-installed using Ubuntu Software centre, terminal,
and Synaptic, still nothing.

I tried launching from the terminal and got this:

gordon at gordon-Lenovo-U410:~$ everpad
Traceback (most recent call last):
  File "/usr/bin/everpad", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2805,
in <module>
    working_set.require(__requires__)
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 696, in

    needed = self.resolve(parse_requirements(requirements))

resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: PySide
gordon at gordon-Lenovo-U410:~$

As I'm not an expert in these things, can someone tell me what I need to
do to get Everpad working again?

Ta muchly!
