Hoster 5.05 Won't Open

[FRadspinner]

Yes, all updates were installed. To give you a rundown of what happened: I worked on this laptop from the beginning. I Installed Hoster (making all the required changes) and Hoster Lite was working correctly. Then I installed Microsoft Access 2007 which included Access. After that, Hoster would no longer open. I uninstalled Microsoft Office and Hoster would still not open. So, I uninstalled and reinstalled Hoster after this (at least 3 times) but Hoster still would not open. Finally, I restored the computer to the point before I ever installed Hoster or Microsoft Access, then reinstalled Hoster, (making all the required changes) and now it is working.
