Got the iPad back.... the guy would not take a reward.....
I deleted the device, like the tip given above, .... and I performed a backup to my desktop computer. I turned off my home WiFi router, then turned on the iPad. In the iPad I turned off "Location Services" and "Find my iPad"..... then turned on the WiFi router. The iPad connected, and did NOT do a wipe of anything...... I then did a backup to icloud.
When I use the Find my iPhone app on the iPad, it works. When I use my desktop to try to Find my iPad (iPhone) it does NOT work.... and I still have no Devices listed. I changed my password to icloud on both the desktop and iPad.... and that did not help.
So... my only issue now, is figuring out how to add the iPad back to "My Devices", when connected to icloud, via my desktop. (if I'm say that clearly).....
it is giving me a headache.... so, I'll look into this tomorrow..... I'm "good to go", as long as I don't lose my iPad again. (cause I won't be able to find it, via my desktop..... apparently. )
