When is this happening? When you try to load the file? If it is after you have loaded the file, can you just press continue to keep going?
If the file loads and you are seeing an error code, just press continue. If the file doesn't load and you are seeing an error, you likely need to start over. It's not likely anyone can help you with error codes.
