After an unfortunate accident, I'm trying to reinstall Lion on my macbook pro. I held down command R and got to the in "OSX Utilities" page where I tried clicking on the "install lion" key with my trackpad but it didn't work. I could however use a combination of the tab key, space bar,enter, and arrow keys to get the section where it asks me to enter my itunes password to continue. This is where I'm stuck. I can't type anything, click anything and it just gets stuck there. Any suggestions? Thanks in advance.
