Help with Adobe Acrobat 7.0 professional

I have Adobe Acrobat Pro 7.0. When moved it to a new computer I was unable to register it. I contacted Adobe support and they remoted into my computer and resolved that issue so that I no longer received the registration screen any longer. Recently, it began to reappear. Then I noticed that the typewriter tool was missing. Apparently when they did what they did they sent me back to 7.0.0 which doesn't have the typewriter too. I understand if I can get back to 7.0.5 I will get the typewriter tool back but I cannot find any way to do that. Any help would be greatly appreciated.
