Hello all,

I'm in the process of upgrading my cart from 1.39h to 1.5 however when trying to log into the admin I get the following message:

database upgrade required. please run the 1.3.9-to-1.5.0 upgrade via zc_install

The database was successfully updated (twice), cache/cookies were cleared, the front end loads ok, but cannot log into the admin due to the above error. Can anyone help? Thanks.
