ok so i did that thanks! know to instal playonlinux should i use the one on my usb or should i install from ubuntu software center?
First of all I'd like to say that you don't need PlayOnLinux to play your games. Wine is all that is needed, now that you have Wine all you really have to do is double-click the exe to install it.
However PlayOnLinux is a graphical front-end for Wine, but the advantage is that is adds in extra goodies to help your games run better & is easier to use for the beginner. So it is better for you to use PlayOnLinux.
There are several ways to install PlayOnLinux, I recommend this:
1. Open Terminal (located in Accessories menu)
2. paste
sudo wget http://deb.playonlinux.com/playonlinux_karmic.list -O /etc/apt/sources.list.d/playonlinux.list
and hit enter. type your user password and hit enter again.
3. When it is finished enter following command and hit enter
sudo apt-get update
4. When the last step has completed use this command
sudo apt-get install playonlinux
PlayOnLinux should now be installed successfully. You could have also installed from the file on your flash drive. But the advantage with this way is that you'll also get the latest version updated.
