Customer Error Reports

We are able to improve the stability of Maya largely because of the Customer Error Reports (CER) submitted by users of our products. We thank you for taking the time to fill out these reports and ask that you include as much information as possible about what actions you were performing at the time the error occurred. These details raise the value of the report immensely and are very much appreciated by the Autodesk Maya Engineering team.
