I know who you are talking about exactly, you purchased this one:

In order for the Pointshop verion to work, you must contact Blu in a PM over coderhire asking him to send you the new copy of it since the one on the coderhire website does not support the pointshop function. All you need to do is find out what your server is running on (ex. Linux, Windows, ect.) and install mysqloo on it according to the instructions. Unless you get the newer copy from him, you cannot incorporate pointshop with the one you currently have.
