Having account issues

I agree with onyx62is it could be a number of things should try all of those steps

Clearing Cache

Step 1:

Navigate to the far right of your Xbox 360 Dashboard

Then go to SYSTEM settings click on STORAGE then click on The Y button when HARD DRIVE is highlighted for device options and then CLEAR SYSTEM CACHE and then restarting your console. If his solution didn't work try re-downloading the profile.

In my personal experience with my console I once had the same issue, but it seemed to have been related to something much different, out of interest how long does it take you to sign in to XBOX LIVE on your console? When I had the same issue it took forever
to sign in, send a message or a friend request. And while trying to send a message or add someone or even accept someone it wouldn't, but it appeared to be down to my connection to the internet being severely laggy. I checked my router to see what was going
on and it was severely over heated. Since I let it cool down from weeks of suffering it signed in to XBOX LIVE pretty quick and I could send messages with no errors at all, and the same with accepting friend requests or sending them.

Let me know how it all works out!
