Question about SafeCast

[ycloud]

The target I am working is protected by SafeCast(or FLEXnet) 2.60.30
I saw "SafeCast" and "FLEXnet" in the dlls.
Can someone tell me the relationship between SafeCast and FLEXnet?

I searched but I can't visit hxxp://tsehp.cjb.net
Maybe SafeCast is too old, can't find toolkit or api guide
Now I have no valid registration code, is it possible to unpack the EXE?
And how?

thanks
