Matrix mode not working

[hh221165]

First of all I would like to say that I am not a programmer, I would call my self an experienced user. I am just curious if anyone manage to get his password back with this tool? I did not get it working at all on a Windows machine, but got it running on Ubuntu I made some tests and it seems that the tool is not to work correctly in matrix mode. I made a view tests by creating hashes with the official PW checker from Tezos. I tried to keep the password as simple as possible to get some results. Unfortunately it seams not to work. If for example I choose a PWD like "lKghf@" and split it up into these parts "lK", "gh", "f", "@" it should be fairly easy for the tool to crack it, but it is not giving any result. It stops with 100% | ETA: INFs | 7/5 and nothing else. No result displayed and CPU goes to 0. if the password is more complex such as "lKghf@GH654" and split it up into this matrix "lK", "gh", "f@", "GH", "65", "4", it just keeps running for ever.
Does anyone have any advice?
By the way, it seems to work correctly, if you provide a password list
