Fundraising not logging donations

We have a client using the fundraising plugin to receive donations through paypal. It looks like the transaction is completing properly but the plugin isn't logging the transactions. I've tried a few times but all I get after completing the transaction is "Oh No, we can't find your Pledge. Sometimes it take a few moments for your Pledge to be logged. You can try refreshing this page" I've been refreshing for about an hour and nothing has changed yet.

I did some digging in the plugin and found that it seems to be expecting a post of type 'donation' to be created with the name of the pledge id but no such post is ever created.

Has anybody else encountered the same problem or have any suggestions for a fix?
