I have been a part of ADE for many years with a Sony EReader.  Today I purchased a Kobo and am setting it all up.  When I got to the part of sync with the ADE it says that my email address is already used, but had to reset my password.  it sill will not let me authorize my reader with ADE as it says there is an error with my name and password.  Updated the 3.0 version of ADE also
