[I can't log in to my account, I've tried every single viewer and nope , no success.]

I am having the same issue, the thing is my sister and friends have no problem from my laptop, so I know its not a computer issue, but something with my account. If you figure out what your issue is, please share so maybe I can try whatever helps you get back on.

I will do the same, if I figure out why and it might be something for you to try as well...

I already submitted a support tkt to LL, just waiting on a reply. 

[Unable to log on to Second Life on any viewer. My friends have np on my laptop, its just me]

Hi, not sure if I am in the right place since my problem is not with the Second Life website at all, its with accessing Second life. I typically use Firestorm, but I downloaded the Second Life official viewer thinking it might be a viewer issue, but the same thing happened.
In all incidents, I am not getting any error messages, my account just keeps crashing the minute it finishes loading in-world.
I go through the login process and then it just closes. I thought it was a laptop issue, but I had my sister and some friends log in from my laptop and they have no problem accessing their accounts and staying on.
I checked my email and the SL website and I don't see any messages about me violating any terms of services, which I haven't. So, I don't understand what is the problem.
I also checked the wiki and all the other links that are suggested for help when encountering problems, but they all refer to different types of error messages and I am not getting any.
Hopefully someone can help me with this. Thanks in advance. :matte-motes-asleep-2:

((I'm on a 2011 MacBook Pro and until yesterday I had no issue accessing Second Life.  And I have also tried on other computers, but it seems to be something wrong with MY account... ))
