Homebrew Smash Dump using DDD 5.5.2 error

[bluemoone]

It seems to connect to my ipv4 address fine, I load the game and it freezes for about a minute before titledumper.exe crashes. CMD Window:

C:\Users\...\Desktop\dump>titledumper /vol C:\Users\...\Desktop\SmashDump (smashdump being the folder name where i want the dump to be)
Title Dumper by Dimok

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

And the application crashes, with smash loading normally. Any thoughts? I have tried several times.
FYI, I'm on a university wifi network, so if there is a connection issue I'm not sure what I can do about it.

If you have a large enough SD, it's easier (and much cleaner) to just use disc2app on the console (or download the game on a computer) and extract it via JNusTool on PC
