Electrohouse Voice Recognition V3.1 Timeout in the exact same setup as before

I'm trying to train my elechouse Voice Recognition V3.1 module, which I have done sucessfully before, but now, no matter what I do, I get this message.

Elechouse Voice Recognition V3 Module "train" sample.

I used the same method with the same arduino, with the same power source and connection 15 days ago. The electrohouse voice recognition module V3.1 is connected to arduino micro in my case. I am using laptop as my power source. The connection I am using is:

voice module RX-> 9
voice module TX-> 8
voice module GND -> GND
voice module VCC -> 5V

I made sure the connections were right and I even checked the values I was using in the vr_sample_train.ino to set RX and TX. Still, I am getting timeout, clear recognizer error etc. Please help.

Best guess: you have to fix your wiring.
