I'll help you continue working with your bank feeds, EJ.
This error appears when the system can't access the fiblueprint.xml file due to user permission restrictions. It usually happens when you use QuickBooks in a hosted or terminal service. Another possible reason can be that your computer has damaged Microsoft components.
To isolate the error, just ensure that you have the appropriate user permission. You can follow the detailed steps on this link and drill-down to the System.TypeInitializationException section: Fix System Exception errors.
Keep me posted on how this works and if there's anything else that you need help with. Take care!
