Shouldn't be a problem, besides it's not a big risk, there's nothing to lose, right? The programmer is dirt cheap, just buy it and try it.

I didn't even tried to download this archive - 1.08 MB is not a good read, it's too small and probably almost full of FF, did you used verification?
Read the chip at least twice, and compare both files. Use verification.

Edit: 4.02 MB is much better
