Shader ran into this same issue earlier. Here's the skinny: Premium's must have an Invention License or have the proper Vet Reward to use IOs. You can purchase the Invention License for ~$2 per month (160 points for one 30-day license), if you don't have the Vet Reward.
I don't know what tier the IO reward is in, but I'll check and get back to this when I do.
