Seems like ZaTii is someone you shouldn't trust big time in the LC community. Here he's sticking up for Whazzert (his best friend) claiming that the resolver works for him.
Clearly it doesn't work, you can scan through the decompiled source code of any of the three versions (I have attached two paid versions below) for the XOR key and you will not find it (be aware these files may be malicious).
Also keep in mind ZaTii is one of the few who vouched for Whazzert back when he first made his sales post. ZaTii is also responsible for 'selling' copies of the 'Packet Resolver'.
None of these three guys are trustworthy and this post alone should be enough to strip any credibility that they have left.
