I didn't know how else to counter an issue I was having with GoodReader, so I deleted it from my IPad, intentioned upon re-installing it. What had happened is as follows:
I had put some PDF documents on the IPad for my wife (to while away the time between some of her collegiate classes, tomorrow) and had pulled a couple of them up to see if they would indeed display properly. While checking one of them out, I happened to accidentally hit one of the buttons that was revealed in the Menu panel, which displays when you tap at the bottom corner of the screen. The page then turned a light tan color, with (what appeared to be) a reddish, brown color for the text. I attempted to return to the basic display coloring by tapping on the same lower portion of the screen. But I could not get the 'Menu' panel to present itself long enough for me to choose an option. It would show, but so very briefly that I could not select anything within it. So I uninstalled GoodReader.
I had thought that going back to the App, in the App Store, would be all that I had to do; figuring that I could just re-download it freely. But there was notice of 'Buying' it.
How do I go about getting it back?
Also, I hope that I haven't fouled things up, with my IPad, because (ever since then) I have been faced with notification of my IPad not being able to be synced.
Things are back to normal, now. After detaching & reattaching my IPad to the PC, I found that there was no longer an issue with syncing. Also, after dancing around a bit within iTunes, I was able to see that GoodReader was indeed there. I just had to tick the box next to it. But thanks anyway.
