Hello @Kahwai48. My apologies for the inconvenience.

 

Note that to open the room, you need to find two computers that send the message to the guards. 
The floor James is on has one of the computers, but it is randomized between Jessie and James. 
 

Can you try getting to the computer Jessie is blocking and seeing if that’s the correct one?

Check out this guide, maybe it can help.
