Bf V Javelin Anti Cheat - fixed after 4 hours of troubleshooting

Not my screenshot, just found it on the web since I wasn't at my computer - I've got just TPM 1.2 for sure.

Anyway, I guess that's just one possible reason for this issue considering the reports from other people - of course you don't get any sensible logging with this tool, so there's no way to get any insight into what the real error is.

 I've created this post, since I saw that basically no one reported this as a solution that worked for them, and maybe it'll actually help someone.
