    Level: 6/10 ? Language : MASM Platform : Windows 32 bit OS Version : Tested on Win10 only, Win 7 and 8 also probably work Packer / Protector : None Description : Mostly simple math algorithms; it includes one relatively small hash part that's mostly isolated, so you can choose to ignore that part and focus on the remainder of the serial. I reckon the number of valid serials will be relatively low. Hopefully I made no big mistakes. Provide a valid pair of name and serial, or better yet write a keygen Good luck.
