Help! Leader Impression 7 PLEASE?!

I just recently acquired an Impression 7, and am unable to download anything from the slideme market. The internet is slow or freezes and I have done everything to restore to factory settings and then update it just to make sure there was nothing on it from the prior owner that was impeding it's performance. I am at a loss and about to chuck it out the window. Did I get screwed when I bought it or is there some way to fix it? Also small words and simple instructions will be needed. I am just not tech savvy at all.

Ps I also get the "Parse error: there was a problem parsing the package" message and I have no clue what that means other than something doesn't work.

 

It's made by "Leader" their customer service is pretty great but right now I can't call customer service because it is off hours. I was trying to find a way to fix my tablet before I had to try and figure out how to get it serviced without a receipt. I bought it off of someone here in town it was a FB classifieds thing.
