I press the Change Level in the menu, but the box won't pop up. All the other boxes in the menu work. It's just the Change Level one.
I am at cl 9.9 and have been able to change my level many times before. I noticed this yesterday. The box just wouldn't appear. I have refreshed and changed servers both to no avail.
I did attempt it on a different browser, Safari, and it popped up there, but I use Google Chrome as my browser of choice. I would like to continue doing so.
Update: This problem was solved when the servers were changed. Thanks for the help everyone!
