I keep getting this error and this is no way accurate and I CANNOT read any of my clients submissions. What is happening? How to fix this asap?

Bandwidth Limit Exceeded

This link has generated too much traffic and have automatically been disabled.

Our sincere apologies. The file should now work once again.

The error was due to the bandwidth limit which has resumed its operation and now affecting uploaded files with high bandwidth usage but it was reverted back to prevent further issues. Should be fine by now.

Thanks!
