AM335X: SD boot card for Android

The Android OS SD card that came with the starter kit got corrupted so I'm trying to reinstall
the OS on the card. However I'm running into a couple of issues.

I am currently using Ubuntu 12.10 to create the boot disk as instructed on the wiki page:
 http://processors.wiki.ti.com/index.php/AM335X_EVM-SK_Android_Devkit_Guide#Preparation_of_SD_card


Here's what I've done so far.
1. Downloaded the prebuilt images: am335xevm_sk.tar.gz
2. Extracted the zipped file and got the folder: am335xevm_sk
3. Used GParted Partition Editor to reformat the sd card : 7.40 Gb Fat32
4. Opened terminal and changed the directory to the folder: am335xevm_sk
5.Ran the line: "sudo ./mkmmc-android.sh /dev/mmcblk0" 

I then get this message in the terminal:

lightace@ubuntu:~/Desktop/am335xevm_sk$ sudo ./mkmmc-android.sh /dev/mmcblk0p1
Assuming Default Locations for Prebuilt Images
All data on /dev/mmcblk0p1 now will be destroyed! Continue? [y/n]

[Copying all clips to data partition]

umount: /dev/mmcblk0p13: not found
[Done]

After this I went back into Gparted and the disk file system is set to unknown instead of Fat32. 
Size is 7.40 Gb. Status: Not Mounted.

Could someone please tell me what I'm doing wrong.
