Hi there,
I want to upgrade vb 4.2.2 to vb 5.1.6
Upgrade starts and stops at 16% (step 142) by with error:

1Unexpected Text:
<?xml version="1.0" encoding="UTF-8"?>
<upgrade>
</upgrade>
<fatal_error>
<description>23 occurred in /home/arshadeomran/public_html/core/vb5/route/channel.php in line 23</description>
</fatal_error>


Also I have recieved another error from Database:

If you look at your user table, what is the lowest userid for an administrator (typically "1", but not always)? Make sure that userid is entered into the /core/includes/config.php file as a Super Administrator.

Thank you very much
