An unexpected error has occurred:

See above for debug info.

Does anyone know how I can fix this? I was able to import data before with no problem and now I keep getting this error.

We have a patch coming out for this today hopefully. I am assuming you are on a Mac, which clean up temp files that have not been changed or opened every 3 days, so part of the new caching system we just released was getting removed by the OS automatically and causing this problem. The short term fix is just restart your computer and it should completely clear the temp directory out and start a fresh cache!
