Radare2 Reverse Engineering: Ep.2 – Windows Binary Part 2; Final Question

I have managed to find the answer to Questions 1-4 of this lab, however I can't seem to identify the answer to the final question (Question 5 - What is the token?). I have run the binary and I get the “You have not met the requirements” message. I understand that there is an some type of execution error within the binary that I must correct for it to work properly however I have not been able to locate the error in order to analyze it and attempt to correct it. Any insight or guidance on what I'm missing / doing incorrectly would be greatly appreciated. Thanks in advance.

I am not getting a prompt to provide the password.

I am not seeing the prompt to use the calculator to find the answer to the calculation that is presented.

I can see that there is a reference to a token.txt file but I can’t seem to get access to the file to determine what the token value is.
