XF 1.3 Upgrade error

Just uploaded all the files and begin the update, when I got this error message. Any help would be great.

Fatal error: Class 'XenForo_Template_Compiler_Function_CheckedSelected' not found in /home/xxxxx/public_html/library/XenForo/Template/Compiler.php on line 149
Funny thing was that not everything uploaded which was why I was getting the errors. I always upload everything in the folder, I guess it was just a hiccup. Thank you both though very much.

Which FTP application do you use?
If you run Windows, I recommend WinSCP.
Never use Filezilla, it is notorious for issues such as this.

There are some errors in there having to do with the add-on Widget Framework. Post in its dedicated support thread for support with it.
