Ok, Here goes. I have had a problem with QQ. At my office I have windstream as an isp. On my laptop I can hear and see her. I go home and cannot hear her. I tried different computers, different settings. Every time it would work on the test then the minute I connect to her bam it is gone. Gone direct and gone through a router, different Operating systems. All programs up to date. The strangest part is sometimes it would work then it wouldn't. It worked initially for about 3 months. I talked to her in the AM, that afternoon I tried again, not having touched the computer in between, then it didnt work. Dinger has tried to help me. We thought we had it working then nope. It has been driving me crazy. Finally I went to my ISP, optilink. Sent a message to their help desk. They said i need a static IP. They would give me one for free. They said to pop that in my router and it would definitely work. I haven tried it yet as she is in Wuhan getting things organized for our wedding. I will let you know though so anyone else having that problem would know what to do instead of racking their brain for about a month.
I have also tried to get my daughter set up and the registration said the same thing, system busy try again later.
