Replaying Bag-file... requires hardware to be attached before replaying messages [closed]

I'm trying to replay a bag-file which contains data acquired using a Phidget 8/8/8 Interface Kit and Flexiforce Sensors. I was able to record the bag-file just fine. However, when trying to replay the file, I receive this error message:
ERROR: Cannot load message class for [phidgets/interface_kit_params]. Are your messages built?
I've tried starting the Phidgets Interface Kit (rosrun phidgets interface_kit) but this script requires an interface kit be physically connected during initialisation. Is there a good way around this? I'd like to be able to replay the bag-files without having to have an interface kit physically attached... so that I can convert the bag-files to CSV files for later data analysis.

Actually it does not require the hardware to be here, but it requires the phidgets package to be compiled. This is to workaround this kind of issues that a good practice in ROS is to make a dedicated package for messages and services. As this is apparently not the case here you will have to compile the whole package anyway. Once this is done you will be able to load the messages you want.
