Upgrade 4.1.1-4.1.2 error
Step 14, message:

Moved to correct forum...

Class not found errors typically come from corrupted files or modifications - try re-downloading the ZIP file from the Members Area and re-upload all files (except install/install.php and includes/config.php.new) making sure you overwrite all files currently on your server.

Does this resolve the problem?
