The velvet edition is apparently both the Original game and the Expansion "Pirates of the Flying Fortress".
Do you need the whole game to make a trainer or is it enough with the .exe file for the game?
If its just the exe file then I can provide that.
If you need the full game, the velvet edition is part of the Epic edition which also includes "Castle Defense", then you can get that for $20 at GOG.
Money thats why dude. There German.
My best guess is that something on your side is blocking the trainer from authenticating.
