FYI: I had the same problem and changing TYPE=MyISAM to TYPE=memory did not work.

My hosting service has MySQL ver5.5.21 and I had to change
TYPE=MyISAM to ENGINE=MyISAM
and
TYPE=heap to ENGINE=memory
then all worked great.

You should consider upgrading your scripts for the newer versions of PHP. Or give us options to choose for the PHP version.
