NXPatcher - Create your own pre-patcher & list of Maple FTPs

So I've been trying to use this multiple times but I always get the same error.
I heard of people still using this so I'm pretty sure it's a problem on my side.
It gives me the error 'Out of memory!' every time I try. I've done what the FAQ tells me to do and I have plenty of RAM left over (I have 8GB and about 3 GB was used pre-NXPatcher.

 Spoiler

Since Fiel isn't the extractor anymore he's not as active anymore (for which he deserves absolutely no blame, of course), but maybe someone else can point out the big obvious error that I'm making that I haven't spotted yet.
