I have a similar issue. After Google offered German users to switch from 
googlemail.com to gmail.com, I ran into this problem. The google account on my 
phone is still displayed as "xxx@googlemail.com" and cannot be changed....but I 
guess Chrome2Phone somehow has trouble connecting with this account information.
