Need help tracking down an issue with attempting to join friends

[Awesomeness]

Hi guys,

I'm trying to track down an issue with the game hanging(probably getting stuck at the running man screen) when attempting to join a friend on your friends list.

If this has happened to you, please answer these questions:
1. Where were you when you were attempting to join?
2. What was the state of the instance that you were joining? (was it full? do you have access to this instance? was it password protected?)
3. What was the state of your friend when you were attempting to join? (Were they online the whole time? Were they still in the instance?)
4. Was there anything that stuck out that you can remember that might help?
5. How often has this happened to you? If more than once, can you think of anything that was true each time this happened?
6. How was your internet connection when this happened?
7. How was server performance when this happened?

Feel free to post anything else you can think of that might help me.

Thank you!
