hi Sergey,
i found an error in the code in install.php, in the admin folder:
when the istallation of the gamepack starts, the for loop runs through the queries, and if one fails in turns $success into false.
problem is - the check afterwards is:
if( !success )
this should be:
if( !$success )
also, i think it would be helpfull to preg_match the names of the games not instralled, and display them in the ERROR msg, so that it would be easier to find the problem.
