ok try and provide these:
Provide this:
Which mysql files you are using - this from rufeng ? or this from other releases (like from this forum?)
Account Server if was working before should work as well now ... only thing that can play role are those setup files (login, pass, ip etc)
I suggest you:
Use old checked mysql, old checked account server etc... Believe me - you must be missing something

You just changed something witout providing other necessary changes that could be important in this case
