All of the improvements and updates that pertain to the PIC will be included in the next update for ROBOTC for IFI. ROBOTC is developed in a way that, whether you're using the PIC, Cortex, NXT, ect, things like user interface improvements apply to all of them when they are updated.
ROBOTC for Cortex and PIC is a separate product from ROBOTC for IFI, and does require a different license ID. For existing ROBOTC for IFI users, we offer an upgrade for the cost difference here: http://www.robotc.net/purchase/cortex/
Please understand that adding support for the Cortex took a few man-years worth of development. You mentioned that your original license was for version 1.08 - all updates and upgrades to version 2.0 have been free of charge.
