Error window for no visible reason

[borodin-devel]

MIX archive is marked as recoverable for header and LMD. Recommended method is used. Error window appears during extraction, but extraction is complete and work is done. Recovered MIX seems to have some files with missing names, some files appear to have zeros in them.

I examined that MIX File and gave me some interesting backtrace information:

Using Level 3 Mode: The Garbage Information occupied its own file size during the reconstruction process which misaligned the next remaining file entries. Will be fixed on the next update.

This Garbage Information found at the LookupTable must've been Added by a MIX Protector... If you know something about what MIX protector this is, you might as well share it here(app download link would be better) so that I can reverse its techniques even further...

[borodin-devel]

Sorry, I have no clue about how MIX file is protected - I know only public list of tools here
