My guess is he also disables (a.k.a. stops the component from "existing") whatever normal network adapter, correct? Tell him to not do that. Using a new network connection won't cause any problems. "Disabling" (and/or removing) an existing network connection will cause problems.
Also, make sure you're using the latest version of TurboActivate (currently 3.4.6) and that the customer is using a version of your app that uses that latest version of TurboActivate.
