I ask that because I'm not that good at this sudo thingy. 
Nobody is when they are new to Linux. That being said, if you copied and pasted:
sudo apt-get upgrade into your terminal it would be interesting to see if the solution was that simple.
Be brave, go to your
Menu, up to
Accessories, and down to the
Terminal.
1) First update by typing, or coping and pasting, into the Terminal this command:
sudo apt-get update Then type in your password when instructed to do so. Remember, you will not see your password that you are typing.
Now hit the
Enter key once, and you'll update your computer.
2) Now type, or copy and paste,
sudo apt-get upgrade and hit
Enter again. If it offers you an upgrade, do it -- enter
Y, or
y, and hit your
Enter key.
3) Now type, or copy and paste,
sudo apt-get dist-upgrade and hit
Enter. It you are offered an upgrade, take it again.
Now
x out, or type
exit, and hit the
Enter key again.
That's it. You're done!
Better to spend a maximum of 5 minutes updating and upgrading, than an hour re-installing the darn program. Who knows if any upgrade might help you here or not? But, at this point, what do you have to lose?
You can do this, I'm sure.
Good luck,
