your Jungheinrich forklift dealer is the only legitimate manner to acquire truck doctor and any other proprietary hardware or software.
Asking here is asking in an -open- forum, if anyone can help you avoid the legally allowed methods to get this software.
In other words, you are asking /in the open/ [where google can search it,] if anyone will help you break the law {of who is allowed to sell these things,} and if anyone did help you break the law, then Jubgheinrich could also correctly say that forkliftaction helped you and the person selling truck com to break the law, which could cause forkliftaction's forums to be shut down the way limewire and napster have been shut down in the past.
I have no connection to forkliftaction, other than they have not yet banned me from posting here, but I sure do not want to ever consider that this wonderful (when used legitimately) resource might suddenly disappear.
