Processing error message

I will be using TAPAS next week (Jan 8-12) during the ARL Digital Scholarship Institute to demonstrate using it and rendering TEI files. We are putting together a private project/collection site (, but on the collection page there is an error message that reads: "project with specified did does not exist." After uploading a template XML file ( there is another error message: "collection_dids references collections that do not exist." Since we would like to use TAPAS for instruction and have students upload their files it is important to us that we do not get error messages blocking us from rendering the files. Can someone take a look and let us know what the issue might be? Thank you!
