Android update not proceeding beyond the point of earlier cancellation
Try deleting the temporary file that is 36Mb in size and re-start the download again this time.

Please include the method in how you're downloading the update - if you are using Kies, be sure to exit Kies first completely, then look for that temporary file (it will be in a hidden spot within the temporary directory under Windows - not sure of the path C:\Documents And Settings\Users\XXXX\Local Data ** OR ** C:\Documents and Settings\Users\XXXX\Application Data or similar) 

You can easily find that out by searching for it depending on where the Windows Environment Variabel $TEMP points to.
