AMP version 0.9.1127 should be okay but downloading and reinstalling AMP may solve the problem.
If the character is still all messed up, it sounds like you need to install the AM Menu. Without the AM Menu install you won't be able to open any of the AM rigs and they'll either appear flattened like a pancake or broken. Here is the AM Menu link:
If you do have the AM menu already installed, double check that your login is set properly and if you're getting an invalid username or password message, I would suggest sending in a support ticket and the tech team will be able to get everything sorted out for you.
I hope this helps.
