Following your comment, I went to Task->BitTorrent and still cannot find the button/option to turn on Torrent Exchange? See the attached screen capture
Close BitComet, then go to your installation directory or app data folder, preferably both, (C:\Program Files x86\BitComet or C:\Users\you\BitComet by default) and delete BitComet.xml. Start BitComet and go to options to see if there’s any change.
Please note that by doing this you delete all your settings and you will have to redo any personalized setting.
Right, right, i forgot about that, sorry. The Chinese government didn’t like it, but they don’t have a problem with torrents themselves. Only exchanging the torrents. I may never understand that.
Thanks for resolving this mysterious behavior! Indeed, the cause was due to a selection of a default Chinese language (although I do not think it has anything to do with the country’s network monitoring because I do not reside there). So the only reason would be the combination of Microsoft OS (XP, Windows 7) (on setting the default language) and Bitcomet (who detects this Windows OS setting and automatically kills off the Torrent Exchange option in the option/preference page). It is rather a draconian measure, and this user had never experienced such language/country sensitive twist (transparent and without a clue) in a software before… for my taste, it should not have been done for whatever the incentives or reasons ..
Well, let’s understand that BitComet did not have any choice about this. The government said, "take it out’, so that was the end of the matter, one way or the other.
