Codecs are little pieces of code sitting in the operating system and activated only when a certain multimedia file or a video game asks for them to be activated. This can result in anything from video artefacts only in certain resolutions to sound distortions. Unfortunately, from time to time, software simply fails and there is nothing you can do to prevent it.

In such case, you can try reverting to a previous state by using Windows System Restore. The file has been corrupted beyond recovery and there can be any number of reasons why this happened. As always, the best approach is prevention. Or you can also attach the file to an e-mail and send it right back to yourself.
