The Iridium are missing the CulturalInfluence tech therefor the InformationHubModule never activates.
Quick fix: Attach the module to the MarketingTech.
To do so, make to following change for the InformationHubModule in the StarbaseModuleDefs.xml.
Replace
<Prerequ>
<Techs>
<Option>CulturalInfluence</Option>
<Option>ThePathTech</Option>
</Techs>
<UpgradesFrom>CulturalForumModule</UpgradesFrom>
</Prerequ>
with
<Prerequ>
<Techs>
<Option>CulturalInfluence</Option>
<Option>MarketingTech</Option>
<Option>ThePathTech</Option>
</Techs>
<UpgradesFrom>CulturalForumModule</UpgradesFrom>
