Filemaker Pro And Version 4

We interface cs cart with filemaker pro. Almost EVERYTHING still works great with version 4, all info still imports correctly with 1 exception:

The shipping method (ship type): we used to get that info from order_data. order_data is now "blob". I've been told FMPro can't pull the data form the blob. Is there any way i can change that setting without upsetting cscart, so that fmpro can pull the data?
