Restore "deleted" apps topic

Hi there guys, well, my problem is:
I installed "App Hide" from ThinkYeah, from Google Play, I removed some "unecessary" apps that I was sure to not use, so, today, I remembered that I had deleted the GLTools, and i want to "tweak" gta san andreas a bit, but here's the problem:
I also deleted, to free up some space, backups of the App Hider app.

Some suggestions ?
