Sender are lost !!!!:frown:

It looks like your going to need to write a decryption program. You have the key ( subract 8bit unsigned 4C) so you need to write the program to do the decryption.

Probably, I also doubt that he even knows how to write a Hello World program, or has ever heard of Google.
