Add on to what Taylor said, you should input the Script's name into the search.
I'm going to be honest, I have no clue about this script, never heard of it before. BUT, I can tell you that if it's pulling the way you gain gold and exp from the default RM or has a code that rewrote that part...well then you could fix you're self. It seems like the Starting Gold is set to 100 and the Starting EXP is 25, within the script. SO, if it's the default, then check out the Game_Party Script for gold, and Game_Actor for EXP. The starting vaules are there. Wouldn't be hard to find, nor change. Again I have no idea how this Script works, it could have a whole block of code written for how Gold and EXP is gained.
I hoped I help. I'm sorry if I didn't. Just thought I'd try.
