Sigh!
Although I'm in no way a 'tech guru', I am a moderator with a finite amount of patience.
If you are so unhappy using BitComet as your client (you have previously stated that you are using it at the same time as two other clients), I suggest that, at least, you show that you do possess some amount of common courtesy.
First, by not using offensive words which the forum's system, itself, overrides.
Secondly, have you tried to report your issue to the Development Team directly (albeit in Mandarin, of course...use Google for the translation, if need be, you seem to be quite good at it from your countless references to using said search engine) as was suggested by an Admin?
I have been a resident of BitComet Forums, assuredly, a lot longer than yourself, and I am always amazed at how imperious some users like to sound and, rather than thanking those who donate their free time to attempt to aid others (not being remunerated, by the way), feel it is their God-given right to insult and try to belittle them, just because they do not see eye-to-eye with what is suggested. Thank Goodness that this is not the case of the vast majority of the more than 100,000 worldwide users of this free application!!
It is tiring, however, to read their posts, over and over, just so that they can vent their pent-up frustrations here (instead of head-butting the wall, for example). Everyone here (and I must include users and Staff, alike) are part of a society that is altruistic in their ideals towards this client, and I have yet to hear someone say 'thank you for your attempted help'...without any sarcasm or second meaning.
Third, ever so politely ask for a full refund (oh, wait... you didn't have to pay for it, did you?), and the developers for a full disclosure of the program's code. Would that decrease your infinite rage and please your Magnanimous self?
PD - You mention the red engine light of your car... funny, my old car didn't have such light, and the mechanics could only attempt to solve the problem once they could duplicate the problem itself... it was all trial-and-error, until they were able to correct it. Of course, I didn't try to tell them that they were ignoring the problem, just because, at the beginning, they couldn't duplicate the temperament of my car. Nor did I tell them that all of their 'brainstorming' was idiotic. It was not my place, in my opinion, since I am not a mechanic. What did I do, in the end? Thank them profusely for fixing my car and go on my merry way. There is a Spanish proverb that says that 'to be thankful is a sign of being well-bred' ("Ser agradecido es de ser bien nacido").
Now, go on, and be a gentleman. Good day!
