12.1 Reinstall or can I fix it?

Hi!

I’m using opensuse 12.1 and the Gnome GUI as MonoDevelop was not to pleased when I tried KDE.
However now my goal is to learn a new language and I want to stay in the family so my goal is set on C++ as this is also more multi platform then C#.
And everything was going along great until I was to create a forms application where it was required that I downloaded GTK+ libs to get started.
My computer was running just fine during the installation but when I was done and were looking on some youtube before I was to get started looking at a tutorial my computer locked up (guessing flash).
And after I restarted my computer I got in to the system just fine just missing all my icons on the desktop and my wallpaper (of cause asking my self why) but thought it just was a settings drop.
Got in to Cinnamon Settings manager and saw that filemanager was not activated to allow icons, pushed it and closed.
Nothing happens going back and the box was unchecked again, restarted comp and now I cant access Cinnamon Settings as Terminal says that its a GTK Warning on all of the GUI.
So my question is, should I reinstall the entire system or can I somehow fix GTK by finding and uninstalling it somehow?

Considering cinnamon is a Mint project I assume you have installed 3rd party repositories. I am not sure where to start with what problems you might be having. For example I doubt MonoDevelop cares whether it is run on KDE or Gnome as long as the required libraries are installed. Are you using just 12.1, no 12.2 or tumbleweed repositories? Also did you correctly change vendor to the cinnamon repository so all of the required packages are installed? Generally such community repositories are ‘at your own risk’. It might be helpful for you to print the gtk warnings and your current repositories. You can use this to paste information: SUSE Paste

No I’m not using 12.2 or tumbleweed repos only 12.1 repo.
The cinnamon I use is downloaded from openSUSE:GNOME Cinnamon - openSUSE and worked fine until I tried installing devel pkgs for GTK+.
MonoDev for me refused to load in KDE and I think requires Gnome pkgs to load so I thought why not use gnome then.

I’ve pasted the error msg at the place you said here is the link I was given SUSE Paste have not used it before so if I could have done it better tell me.
