@mitu I got in touch with Steven Selph who wrote it. I think he's on top of things now. I got everything to work on my end, but it seems like the module still might need some work.

@andrewpelt The new version of RetroPie-Setup is supposed to download a new version of go to a non-default location and us it to build the scraper. I did this to hopefully make it more stable. Go has a guarantee that new versions won't break any old code. It only adds new features and fixes bugs, but there wasn't a guarantee that code I depended on wouldn't take advantage of one of these newer features and break everything.

In Go 1.6 they added the ability to copy all the dependent libraries in to my repo so now it will always build. I can't explain why these issues are popping up.

Buzz once again you were right. Changed the bloody Kingston with a SanDisk and workd like a charm
