Per PM customer service ( I was just using LiveChat about this very same thing)
Here's the copy and paste of what I was told -
"...You could alter the handling to work with a different number, but 30 plays an important role."
Note: At this time, there are TWO pages if you search Dark Connection. The correct one lists this as an $8.95 Instant download. The INcorrect one lists the price as $89.95.
Don't mistakenly add the incorrect high priced one to your cart - it will post.
Also, this is a pdf download with access to Riboulet's YouTube channel to view a training video which he does not make available to download to your computer. That's the official line anyway.
To get the video to your computer, you'll need to capture the info for later use on your device.
It's an easy process.
