  <p>I've <a href="http://pastebin.com/JfzEtE5P" rel="noreferrer"><strong>uploaded here at pastebin</strong></a> the results of searching the word "error" in all log files generated by genymotion (456 hits in 16 files).</p>
  
  <p>Everybody on the internet praises this emulator so much that i don't want to give up so fast, but I certainly don't know how to fix it. I've googled these different errors, nothing of use.</p>
