Apparently it's some sort of anti-cheat engine (made by SCHTHack) which Wine doesn't like. As I say for now there's nothing that can be done until they remove it.
If it works on Windows and crashes in Wine then this is a Wine bug and not their fault. If their checks are too strict it might be possible that we can not fix this in Wine, but first of all someone needs to analyze the problem. This might be difficult if it is no longer possible to register an account.
Btw, almost all anti cheat engines and clients of commercial mmorpgs use some kind of anti-debugging tricks, obfuscators etc.
