Something went wrong with the download links; the links were still pointing towards the beta. Here are the correct links:

ftp://193.224.143.39/pub/fpc/dist/2.4.4/

and

ftp://freepascal.stack.nl/pub/fpc/dist/2.4.4/

Note:
the main ftp server is currently being migrated, that's why there is a IP based URL above.
