Pin the reset button to reset the tablet and power it on again.

Possible reasons may be that this app is not compatible with your OS or the
downloaded .apk file is broken so you may need to download a full version.

If an account is added, the account is shown in “Accounts & sync” of
“Settings”, where you may also add another account. To delete an undesired
account, go to “Settings” → “Privacy settings” → “Factory data reset”. The
tablet’s internal storage, downloaded apps, etc. will also be deleted at the
same time, except the info in your flash memory. Be careful before you carry
out this operation.
