IP.Nexus Alternative ?

Hi



IS there any shop script that can be integrated with IP.Board beside IP.Nexus



To Explain:



My Forum is hosted on ipage (shared hosting) and their zend & ioncube versions are quite outdated



They dont know when it will be upgraded and when i tried to upgrade it ip.nexus instalation did not detected updated versions



So im searching for alternative and thanks in advance to everybody you can suggest me other script



Another question is : my ip.board version is 3.4.6 - can i use maybe older ip.nexus version that will work with my outdated zend or ion cube with it?
