The error msg. tells us the story.
#1044 - Access denied for user 'yabycosm'@'localhost' to database 'yaby_zc1'
You did not change the db name before importing.
When a db is exported it saves the current db name and access info. If you are uploading to another account you must first make some changes.
As the db is just a text file, open it with a text Editor, do not use a Word Processor, and change this line:
CREATE DATABASE `yaby_zc1`
You need to use the db name of the account you are uploading to.
Also, in your Control Panel mySQL area, you will also need to use the same db Username & Password for access to this db. If not sure what they are you can look in the ZenCart config files.
