Livesey on "[Plugin: AdRotate] Warnings and errors with adRotate 3.8"

Working perfectly before upgrade. Upgraded to 3.8 this morning and now have numerous errors, warnings and notices. Many to do with this:

WordPress database error Table 'wp_2_adrotate_stats' doesn't exist

and

PHP Notice: Trying to get property of non-object in adrotate-functions.php on line 112
