There was no single word about any cracked software.
WinOLS demo is free.
TunerPro is also free.
Free as in beer does not grant you the right to reverse engineer or modify the software.
EVC is German company. How would they "hurt" this forum in any way and why would they do that in the first place?
By filing a DMCA notice, it does not matter that they are a German company.
Opening OLS file in third party software (hex editor, script) and looking at it is not a crime or is it?

Anti-circumvention clauses of the DMCA prohibit circumvention of “technical protection means”, that limit access to the copyrighted work.
Having OLS files in an obfuscated and encrypted format is certainly a technical protection.
Not being able to export things from the demo, is again a protection and bypassing it falls under this clause.
Reverse engineering OLS and making an OLS -> XDF converter, which EVC actually sells for 150 EUR is also a great way to get the wrong kind of attention.
If you are not familiar with DMCA and do not have experience with it, then hush. It can be used without any legal grounds by the copyright holder and it is up to the admin to prove it is not the case.
Until the admin does that any ISP in the US immediately takes the site down, and does not put it back up until the content is removed. If they don't, they can get sued.
Having been on the receiving end of the stick, it's not a fun thing, and fighting it is usually a waste of time.
Since we don't have an active admin, if it gets taken down, then it might be down for weeks or months.
I've actually thought about dumping this forum and re-hosting it somewhere, and giving some people actual full access to the server itself, so it does not suddenly go the way of the dodo.
