Every script failes....

Hi

One day here, I tried some python programs, that needed python 27 and python setup stuff.
After I uninstalled this two programs no script works anymore in XBMC.

I have deleted everything that had to do with what I tried, but this don`t help.

What have I done? And what can I do to fix this?

Here is my log, I have finally remembered that this always is needed.

I have tried to understand the log, but no luck for me here..
