C++ Boss Reward System (Working in 1.4.2)

[OTcreator]

Welcome.
The script was created by @ohman and customized for BlackTek, which is based on TFS 1.4.2.
Unfortunately , some of the changes to BlackTek in C++ caused , that the code can not be compiled (error).
Is anyone able to help so that the code is functional in the base TFS 1.4.2?
