Error pulling up in datahub

I got the following error trying to pull up the repo in datahub:

@meiqingli log into the datahub and see if you have an old copy of the repo there.

If so, just rename it (or delete it if you don't need the old version), and then try connecting to run it again using the datahub link.

I've had this issue before and resolved it exactly as @aculich explained!

Meiqing and I are meeting today to make sure deleting the folder resolves the issue. I'll close this issue once we confirm that things are working.

Our returning-participants are likely to encounter issues like this, too, so we should figure out a very simple, quick, and easy way to 1) make instructors helpers aware of this; 2) communicate ahead of time and at the start of a workshop for people who may have used the datahub in the past; 3) make sure helps can quickly troubleshoot this with people during the workshop (if they missed the earlier warnings).
