account assistance bar brief browser caching code containing copy date download email ensure error file files fixed forward free glitch invalid issue link links merchant overwrite panel press process promptly rare refreshing remains returning send system tonight unable updated upload url users

I'm currently unable to overwrite files in my account. After the upload process, the date the file was last updated remains the same. I've tried refreshing the browser to ensure it is not a caching issue. Also, the download links being sent to users created via the "Send Free Download Link/Code" panel are returning the following error:
"This is an invalid download link.

Please copy the link from your download email, paste it in the URL bar and press enter.

If that does not work, please forward the email containing this link to the merchant for assistance."

Any idea why?

We did have a brief, very rare glitch in our system tonight, which we promptly found and fixed:
