The above links detail sync speed, high sync speed, hypersync and how it interplays with Einstein. It is a very complex explaination that cannot be fully repeated everytime the question is asked. However, the first thing to try is setting Einstein to full power.

Tried to set to full power, nothing happens

What firmware version is in the MC2? Should be 2.200

Also, make sure it says CTL-01 on the back LCD instead of CH-01 for the channel display. You need to be using the ControlTL (CTL) channels, not the legacy PocketWizard channels (CH) (which would make the flash fire when using a Plus II).

And make sure the firmware in your triggering radio is updated to the latest (6.0 for Canon, 3.003 for Nikon).
