Hi Returnee. To help you out, go to your PinballX folder, and you will see a Config folder at the top. Go in there and you will see a file called PinballX.ini which is what you need to edit.
Open that with notepad or whatever you use, then scroll down about halfway, and you will find a section that starts with [FuturePinball]
5 lines below that you will find the line you need to edit.
I can't remember the original line, but the line should say
Parameters=/STAYINRAM /open "[TABLEPATH]\[TABLEFILE]" /play /exit
Change yours to the same as that and save it, then you'll be all set.

I hope that helps you out. Cheers, Mal
