The problem with the crack is that only the german version seem to be protected.
English/US version has just a CD Check, Spanish version too.
The CD Check is in Starfighter.exe. So the crews cracked this cheap check.
But in german version is the second exe (Europa.exe) protected by Safedisc 2.51.021 ! So they should unwrap this, but they probably don't know about this and do not have the german version, so..............well.
Burn it or.....
