Rooting an MPman Android tablet

Hello everyone, I have just received an Android MPMan tablet, a MPQC 783 IPS running Android 4.1.1. I wanted to root it to install Linux on it, so I enabled USB debugging on my tablet and tried to install the drivers. Windows 7 told me that the drivers were not found, so I had to use MoboRobo to install a driver. Then I attempted to root my tablet with UnlockerRoot, but it said it couldn't find my tablet, so I tried with Kingo Android Root, which correctly detected my tablet and seemed to root it properly. However, at the end, when I reconnect my tablet to see if it is rooted, it tells me that it is not (it shows a big NO). Then I thought that the drivers MoboRobo installed might be wrong, so I searched for the drivers for my tablet online (also, the CD that came with it contains only the manual, which does not indicate where to find the drivers), but I found nothing, not even on the official MPMan website. I'm stuck; I can't root my tablet even though I followed all the information and tutorials I found. Does anyone have a solution, please? Thank you!

PS: Maybe all this is only because I might not have the correct driver, but I couldn't find the drivers for the MPMan MPQC 783 IPS tablet. If someone finds them, please give me the link, thanks!
