Locked out of a company

SUGGESTED

We are still running Peachtree 2011 and have two companies created. Our power went out the other day and the computer died and now I can't log into the company that was open at the time. It keeps telling me another user has the company open and I must log them out first. However if I open the other company logged in as Administrator and look at logged in users for all companies it only shows Administrator. I tried "Log out all" but it still doesn't work. This is the only computer that Peachtree is on so it's definitely not open on another computer. 

  If this isn't the right forum to ask about this could someone please point me to where I might find help? We desperately need to get into this company. Thanks in advance.
