Error while trying to pwn my 3g with WinPwn. Would really appreciate help!

Once I did all the settings for the iPSW Builder, I tried to save it and got the error, "Failed to create custom IPSW! Do you want to close the IPSW builder?"

I'm in dire need of help.. the only thing I thought that might have caused the problem is that it doesn't seem like I have anything that can open the BL-46 and BL-39 images, .bin is a weird extension .

Is that it? Or is it something else?

Let this thread die please, I downloaded a .bin viewer and whether or not that did the trick it worked this time.
