Frequently Asked Questions
It sounds like you have probably removed the animations inside the AO by accident. They are most likely in your inventory, if you put them back inside it should work again. If you are unable to put them back in please contact me and I will do my best to help.
Sometimes LL will remove animations if they are illegal pirate copies too. If this has happened you should find an animation that rotates your avatar inside the AO with a name that says it is an IP replacement animation with a number following it.
