Have you tried the following:
Right click the executable and go to properties and set it to always run as a administrator and in xp compatibility mode.
If you once ran it without compatibility mode, there is a high chance the settings got changed to exceptions instead of hardware breakpoints, so best check to make sure you use hardware exceptions.
Settings: Don't use the process watcher or stealthmodes. They don't work in vista.
PS: Is there a way to make Wolf Team into an .exe? Because i want to start hacking it but I'm stuck at the moment.
