I'm surprised anyone posts on Coppermine's boards - that GauGau fellow has almost zero social skills and really shouldn't be on the Internet dealing with human beings at all. It's a capital offence to ask the same question twice with him. Unbelievably uptight individual...
Yes, Coppermine is a GPLed product and they don't *have* to help you with anything, as the software comes with zero guarantees.
My advice is to migrate to Gallery. It can do anything Coppermine can, is free and the support crew are infinitely more welcoming and friendly.
I know this at first hand as I used it for over four years.
As for not knowing any scripting, not even a skerrick, I recommend you do learn at least the rudiments, as *any* tinkering with a complicated PHP script like Coppermine or Gallery will involve some knowledge of what's going. It's inescapible.
