I'm having the same problem. I received the email, had to download and install Impulse. I made sure to check the "show pre-release versions" and restarted Impulse. I had ObjectDock Plus 1.9 installed, and tried (unsuccessfully) to uninstall it before Impulse, but that didn't work. Anyway, Impulse detected ODP 1.9, when I clicked on Update, it only downloaded 1.9 again.
Edit: Nevermind....I used Impulse to uninstall v1.9, then went into Registration and entered my new serial # for v2...had to scroll down the list a bit to find v2 and installed it from there, then clicked "Run" in the bottom right corner. Works fine now, even managed to keep my previous dock skin and icons intact.
