PgAdmin crash on windows 8.1

Hi,
PgAdmin 3 stops at the application launch in Windows 8.1
I think it's related to some windows update because pgadmin was working fine a month or two before
I can not say exactly when this started to happen because I do not using pgadmin so intensely lately.

I was using pgAdmin 1:18, I tried to repair the installation without success.
Then updated to version 1.20 but the problem persists.
The windows application log says:

Can anyone help me?

Thanks in advance
