I'm in trouble. I uninstalled the actual TTHome; downloaded and installed 2.7 from the above spoiler; applied the patch; run TTHome2 and an error occurred ("server : null"); I ignored it and proceeded, being able to uncheck the TOMTOM WORK (an update to navcore) flag.
BUT no map update occurred and, worse, the request to update to 2.9.8 appeared and, if canceled, TTHOME shut down.
Where did I mistake ? Furthermore what do you mean by "you need to edit the file as instructed, or apply the patch below to antiupdate " ?? I was unable to find any "instruction" and "below" there is only the spoiler to TT 2.5.
