Okay, sorry if it sounds like I'm asking a dumb question, but has the interest batch been posted?

Also, when you ran the Interest Batch, did you select to charge interest by Billing Cycle or by Customer (customer is only available if you've selected to 'Clear history by Period End' in your Company Profile)? If you selected by Billing Cycle, perhaps you need to also run an Interest Batch and post it for the other billing cycle(s) in use in your company or for all billing cycles (eg. 'blank' to 'zzzzzz').
