Topic: OFX info for Del Norte Credit Union

I'd like to begin using GNUCash with my credit union but I don't know how to obtain the OFX information.  I've already reached out to the credit union and they reached out to their online banking provider, Digital Insight, but they wouldn't let me talk to DI directly.  They were unable/unwilling to provide me with the info I needed. 

What's the best method to go about to try to figure this info out on my own?  Does anyone here have experience with Digital Insight? I'm assuming there's probably a standard configuration and we might be able to guess some of the information based on other info for banks/CUs that use DI, but so far I've had no luck on my own.  Any help will be greatly appreciated.  Thanks.
