When upgrading from Adobe Acrobat Connect Pro 7.x to Connect Pro 7.5, the update script goes through a process to correct or update permissions for all Archives in the system. In some use cases, the public Archives change to private.
To correct this problem, change the permissions on affected Archives to public:

In past releases, Adobe set different permission IDs in the database for Archives, which Adobe is correcting in Connect Pro 7.5 by setting the same IDs. Adobe is setting the Archive permissions to be the same as the parent folder; the parent can be either a Meeting or a folder.
If you need assistance with changing the permissions for your Archives, visit the Adobe Acrobat Connect Pro Support page and call Support.
