I had planned on just deleting stuff i didn't need on my LE1700 MotionComputing tablet, and i stupidly followed steps i found online to get everything off quickly, now none of the drivers work, it can't use wireless, there's no brightness settings and it's almost too dark to see, no sound, the pen doesnt work and i'm trying desperately to reinstall stuff, and none of it's working. Am I just starting in the wrong place?? I really need this to work, i've been making my money off selling art i made with the tablet. Need help ASAP
