Welcome @jperkins
The UseGalaxy.org server was under heavy load yesterday and we have applied some changes. Trying to load the data again is where to start!
Then, if these files are still not completing (in the history), would you like to explain more about how you are loading and what these data files represent? Overall size and the type of data? How many?
Alternatively, you are welcome to share the history back here for more specific feedback. How to generate the share link is here.
If you solved this already, please let us know!
