    This IS my website and the program I believe is pretty secure, however if you can crack it, I will give a small $50 usd reward out to the first person to do it. If you are interested in trying PM me and ill set an account up for you on my application. It is for a cheating site. I sell hacks for games such as battlefield, counterstrike, call of duty, etc Sic_2.0_Setup.zip

    Hi to everybody. Here is a small old year - new year present to fill those empty moments in this dark time of the year. Happy living to all. The unpackme was protected by a stripped down version of lARP 2.0 (lena151's Anti Rip Protector). Unpack/deprotect the unpackme and the first to succeed gains a kiss on the forehead from me (or perhaps this is a good reason not to try it? ) Success to all, lena151. lARP_2.0_Unpackme.rar
