[C#] Proxy Client Crash
I made a simple proxy (Silkroad Security API with some of my code and some of SRProxy API)
what i basically did is I Made a proxy between me and sever and then i passed Packets
What i need help with is whenever i login and choose char i get crash
i have tried many things but never worked here is my code , Hope anybody could tell my why i get this random crash
Oh and i found out that the last packet OPCode was 0x2114
PHP Code:
const byte SRLocal = 18; //18=iSRO,40=rSRO
const int SRVersion = 416;
