I don't know if this is too technical a question to ask in this thread, but I'll give it a shot.  I'm in charge of computer allocation at my company, but I'm not an IT guy by any stretch of the imagination.  We hired a gal in December who quit in January; she was issued a brand new MacBook Pro and shipped it back to our office this week.  She had a password on her account (the only admin account; I don't do anything with the computers before I give them to people, although apparently I should) and would not return my calls or emails asking for the password. 
Because the system did not come with a Lion install disc (WTF, Apple?) I did some Googling and found several sites that recommended booting into single user mode and entering the following code:
	
	
	
		Code:
	
	
		mount -uw / 
rm /var/db/.AppleSetupDone 
shutdown -h now
	 
 
I did that and it seemed like it worked the way it should, but now when I boot the computer, it just sits on the gray screen with the Apple logo while the little wheel thing spins forever. I've looked all over the place, and while I can find a couple other instances of people having the same issue, I haven't seen any suggested solutions.  Does anyone here have any suggestions?  Right now I am assuming I'll just have to take it to the Apple store in a couple weeks when I have the time, but I thought GAF might be able to assist me sooner than that.
Thanks in advance for any help.
