Unable to download files anymore

Troubleshooting already attempted:
- restarting computer
- clearing cache and cookies
- trying different files to download
- using private browsing
- using DIFFERENT browser :')

I get the following message

"You're currently downloading for the .

Please wait for your download to finish before starting another.

If you're not downloading this, please click here to cancel your download."

Even after pressing cancel your download it says
"Error: Unable to cancel your download. "

Has anyone else had this problem and fixed it?

TIA
