Ive got a slight work around working for now. I haven't tried all features but its a start.
In wp-content/plugins/nextgen-imageflow/admin/admin.php
Line 47 comment out this line to look like this.
//$flowCheck = new CheckPlugin();
Your adding the 2 // to the beginning.
On line 53 do the same so it looks like this.
//if ( $flowCheck->startCheck() )
Again add the 2 lines at the beginning.
That removed the version checking for me. Im no php coder but its working for me now...
Good luck...
