Just installed WOW. Cursor won't move

Hi, everyone. The hard drive I had WOW files on in my desktop (I have two drives) has failed, so I reinstalled WOW on the working drive. Install went fine, and all patches downloaded. However, When I start up the game, it plays the WotLK intro video (Arthas waking up on throne, stabs ice, dragon appears, etc, etc), and then it goes to the User Agreement page. Here the cursor will not move at all. I tried tabbing down, arrowing down, page down and all the other buttons, but I can't "agree" to the User Agreement, so I can't finish a login. I read on other forum post that this usually means something is wrong with the config.wtf file. However, because I can't log in yet, there is NO config.wtf file in the WTF folder for WOW. Anyone computer geniuses fell like pointing me the the right direction here? (I'm needing my fix of WOW and can't get it.)
