I found this information and I used it, and it worked (I am using Windows XP Home Edition, I don't know if it works for the others). Please follow the steps very carefully.
Open up Notepad, and use a new document.
Type the following text:
REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\CurrentVersion\Run]
"RunDLL"=-
Save the file as: unbridge.reg
Close the file and open it back up, accept the changes and all being well it should have worked.
