the general suggestion by MassIV to:
1. disable the adblock plus component (Tools > Components...)
2. reboot the browser
3. reenable it
4. reboot again
worked for me.
I was then able to click on the little red ABP in the corner and access the chrome://adblockplus/content/config.html to select the filters etc.
I installed, removed, reinstalled, nothing helps.
