Process is blank when open/view in Workbench ES 2

Hello,

I a currently having a problem of opening/viewing any process in Workbench ES 2. It keeps showing a blank page.

It used to work fine before, it just start to have the problem yesterday. No update was applied to the PC so it is kind of strange.

I even tried to reboot the PC, run the Workbench ES 2 as an Admin but it still show a blank page.

OS: Windows 7 32 bit

Workbench ES2 (9.5)

Can any one please advise on how to fix it.

Thanks,

Han
