map extract problem

I have a tomtom xl 330 with us and canada map, I wanted to update my map, so i downloaded the following map

USA and Canada 890.4235 with Automatic Installer & Patcher
; USA_and_Canada v890.4235
11 70 30 F5 9C AD 2E A9 F8 F1 70 6C 75 6E 3A 98 USA_and_Canada-572.meta

but when i was extracting(i am using winrar on win 7 64bit ), most of files were extracted fine, just two of them had problem

! D:\software\tomtom\USA and Canada 890.4235_Installer.part3.rar: CRC failed in the encrypted file USA_and_Canada_890_4235\cline.dat (wrong password ?)
! D:\software\tomtom\USA and Canada 890.4235_Installer.part4.rar: CRC failed in the encrypted file USA_and_Canada_890_4235\cnode.dat (wrong password ?)


anyone can help me with this problem? thanks

Do you extract the files seperatly or you simply start at the first and let Winrar do the rest?
Usually it should work just fine, at this stage I can only assume a faulty download.

Thank you for replying
these are the files I downloaded, they don't look like faulty download to me, what should I do next?

Start the EXE and follow the instructions given by the installer.
Otherwise manually unpack with Winrar, transfer the map folder to your device and ran the latest version of FastActivate.
