PRO SITE with premium plugin - wordpress-form-manager

Hi again guys,
I'm working with the plugin and its VERY VERY good one! love it!!
I've install a plug from WP site: http://wordpress.org/plugins/wordpress-form-manager/
And I set it as a premium plugin (from level 3 and above).I've mark it in the premium plugin list to level 3 and checked the 'Auto Activate' option as well.
Now, When a blog is on level 3 he should have this plugin activated automatically, The problem is there is some DB problem with it and the website is stop working and all I get on the front site is: 'Table 'wordpress_3.wp_53_fm_settings' doesn't exist'

I've checked it up a bit and find out that when I disable the 'Auto Activate' option from the premium plugin list and activate it directly to the site - All works well.
But with the 'Auto Activate' option from the premium plugin list I get the problematic DB problem.
Any suggestions?
