When evaluating the truth value of claims like this, consider a few things--
1. "Comply with Cease & Desist To Re-activate" is rather unlikely for anyone to program as a standard error message. It's also in a slightly different font from the previous part of the message. The following part of the message says "Update Failed"
2. The creator of the video (a rap video creator) could easily generate the situation by playing a YouTube video (that he created) on his screen
3. The letter (possibly based on a real cease & desist) has all of the information concerning the deactivation in a single paragraph, which would be easy to insert
