I got custom tuned and was given the file of my map... its a .hex file. AccessPort requires a .ptm or .stm map to transfer to the unit... any ideas on how to get it on my AP?

It is going to be a PITA to do this. You will need to have the Acess Tuner Race version. This versions does not use the same layout that is commonly used with ECUflash/ECUtek. While the latter use load as the x-axis and rpm as the y-axis for the tables, Cobb uses rpm on the x-axis and load on the y-axis.
Second, Cobb uses lambda numbers (varies from 0 to 1) in the fuel target tables rather than AFR numbers as ECUtek and ECUflash do. I think there are other tables that are different, but I do not remember which ones off the top of my head.
Your best bet is to go to a Cobb AP pro-tuner and get your car re-tuned that way.

Like mentioned above. It can be done. BUT. Is a huge PITA! I have done some further reading and it seems to be very difficult.
