Can you please try the link again? It should be fixed now.
Ok its the right link now, but it's asking for a forth part, I have only got 3 file, the download say it's three part only. So I cannot extract it. It's saying next volume is required (Autodesk_FDSADV_2013_English_Win_64bit.part04.rar
Happy to hear that the download is working properly now. Please let us know if you experience any other issues.
