I have a touch screen bought through ebay, ebay item number 171953596689.
I need a little help please getting it working.
I have found where to download the library componenets and have tried to use the test program "Graphicstest"
When I try to upload it I get the message

With verbose enabled I get

This report would have more information with

option enabled in File -> Preferences.
Can anyone help please?
