I have played this game for about a month.  I was going to use a USB number pad to control my character.  After using it for a while, I decided to switch back to the keyboard controls, but I couldn't reset the controls (with reset button).  I did set the controls one by one back to what they were.  Then I noticed that I couldn't select items or people with the mouse.  I can't seem to get used to typing commands - it just doesn't seem as good.  I can't select items or people with the mouse.  I deleted and installed the program.  I tried it updated and not updated.  I even created a new character with different email and it still did it.  I would like to keep playing, but I haven't been able to get used to not being able to click on things.   Thank you for you time and help.
My computer is a Dell Core 2 Duo @ 2 GHz, 4 Gb RAM, 320 Gb hard drive, 256 Mb NVidia graphics card.  Windows 7 - 64 bit.
