Default [Q] Market Helper ... what am i doing wrong...

Hi,

am I missing something?: I have rooted my tablet. I have successfully installed Market Helper, I have installed the apps i found on google store without problems. But when I try to start it, it doesnt work and pops me an error. I am new to all this, but am I supposed to be doing something else? The requirements of the apps I got are well below the tablet quality I have, but it just seems I cant make anything work, even though I install it. Am I doing it wrong?

Thank you
