6.0.a.3.73 update failing

[#1]

When i plug my phone into pc companion it says there is an update to 6.0.a.3.73 available. It then tries to download this update but comes up with an error message but no error code so i dont know what the problem is. Im in New Zealand but the phones parallel imported, the SI number is 1257-5188.

If anyone could tell me how to fix this problem and also what country that SI number responds to i would much appreciate it
