RPM Gauge stopped working

Hey guys, not sure if anyone encountered the similar issue and experience. I had the latest simhub app installed on my windows laptop last night and appeared my RPM gauge is now stopped responding. I can see the simhub still talks to the board but nothing happen in the RPM/tachometer gauge. I had also tried to reupload the sketch. However, it came up with a window saying "Installing package SimHub.Arduino|DE" then nothing happened again.

Any ideas how to fix this? Much appreciated!
