Audio Synchronization does not work

I got a help request from a colleague saying that he has deleted SAB and needs to use it again. I installed SAB 11.4.3 and then 11.4.4 with sdk, jdk and Aeneas.
When I checked, everything seemed okay.
However, audio synchronization does not show any work, just blank screen like below.

I have tested with Aeneas version 1.7.2, 1.7.3 and All show the same result.
It worked ok on my laptop with the same audio files.
Any advice or suggestion is welcomed. Thanks.
