Hi Jaime,
we won't be able to help you if we don't know what the error is.
What version of Taxi Booking are you updating from?
Instead of user name and password Live update now requires Download ID which you can see after you log in to kanev.com across the top of My Downloads section.
Here is a link to Live update set up again:

If you still have a problem updating please let us know and:
Please provide Temporary back end and FTP log in details to your website in a PRIVATE ticket so we can take a closer look and help you with your issue.
