Help play store wont recognize my acer a500 iconia

[bettynotready]

I just picked this tablet up about a week ago. Nd I can't seem to download anything there's due only to an error nothing specific . I've noticed the play store online and the market app both dont recognize my device. I have my sg3nd lucid witch it knows from my account. So I made a totally new account witch it still won't recognize.I could really use some help.otherwise this has become an oversizes mp3/paperweight....also I've read posts bout the whole update issues nd I can guess to b exited to figure this out nd move on to root:banghead:

You have to connect the tablet to the internet and login to your Google account from the tablet.
