1.16.4 - Patch error

[PanzerKnacker]

Recently I went online and saw that everyone was using a new patch so of course, I proceeded to d/l it myself. I saved and installed it, and when I try to open 'outfront-v1.16.4-editor+mp' I get the message:

'The files are corrupted. Please obtain a new copy of the program.'

I reinstall and get the same message.
Can anyone help?
