You get what when you try to run the updater?

lol sorry a regular 500 error, Internal Server Error

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, webmaster@yp-forums.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

any clue?

Check your server error logs - even in live stable releases, our support for 500 errors is relatively limited, due to the fact it's an issue with the server itself. :) Your server error logs may have more information that can help however track down the problem.
