New waves central crashing Pro Tools 11

I've just installed the latest version of Waves Central, which forced me to re-install all my waves plugins, and now Pro Tools is crashing when I start to use some Waves plugins in a session.

Does someone else experience this problem?

I'm running Pro Tools 11.3.1 on a PC with Windows 7 installed on an SSD.

I tried to go back to a previous version of Waves Central but the installation always fails at the beginning...

Thanks in advance for your help
