Gallery Crashed After Attempting to Upgrade from V 1.1.4 to 1.5

Error Code:
Parse error: parse error, unexpected '<' in /www/f/frenchbulldogz/htdocs/gallery/config.php on line 45

Gallery URL (optional but very useful): http://www.frenchbulldogz.com/gallery
Gallery version: Was 1.1.4, attempted to upgrade to 1.5
Apache version: Sorry, don't know
PHP version (don't just say PHP 4, please): mysqld 4.1.15
Graphics Toolkit: Can't recall
Operating system: XP
Web browser/version (if applicable): Firefox and Opera

After completing the install/upgrade process what had seemed to be successfully, this is my end result - the php error page. Checking the source code shows line after line after line of errors reported - I made a .txt version of the config.php file, so you can see the errors in the code, and I've attached it.

At this time, if these errors are irreprable, I'd settle for someone telling me how to revert to the previous version I was running. I did make a gallery dump backup, but I have no idea what to do to use it. Of course, I'd prefer to get this fixed, but the amount of errors are daunting me!

Can anyone help? I'd really appreciate it.
