[Yameteee]

Sorry to bother u guys,

I have problem while doing hoenn subway quest.

I can't talk to any pc to install the disc wattson asked for:

1. I started the quest & got all 3 pc installed, but

2. After I got the 3rd pc installed in pacifidlog, the game seems freezed, I relog & try to communicate with the pc again but nothing happened(no response)

3. I tried to talk to wattson, he still ask me to find 3 pc.

4. I still can't communicate with any pc for further progress.

 

Thanks for ur attention...
