Here is a AV scan link, no threats. http://chk4me.com/check/public/4wM4pzG985B85a11PVET4 There can be serials fished, also some serials you wouldn't think off at first. Have fun and good luck.

    This is my first keygen-me so good luck. Original Language: C# Difficulty: Beginner to Intermediate Obfuscated: Yes (SmartAssembly) Self-Keygen/IL-Patching: No Not sure if the algo I wrote is used in real software but it works and creating a keygen for it shouldn't be too difficult.
