Upgrade from 4.x to 5.0.2 issues for licensed users

Imported From: http://groups.google.com/group/in-portal-org/browse_thread/thread/fca33306b0ef02ef#

There been several contact us form submitted and some topics added about upgrade from 4.x version of In-Link/In-Portal to 5.0.2 version. It seems, that user have expired support licenses and that's why doesn't see 4.3.1 version at all, that is required to upgrade from 4.3.0 (or older) version to 5.0.2 version.

I propose we check that license is at least present, no matter expired or not and if present, then show pre 5.x versions on module download section. If we do so, then I think we should send reminder email to all interested parties or to all forums users.
