The quota exceeded error means you are out of disk space. 

Google Chrome, Safari and other browsers were recently updated to be much more conservative in how much free space the disk must have for it to store extended caching files which Gigwell relies on.

To resolve this error, clear some unnecessary files from your computer, like downloaded installers. Remember to empty the trash after removing files or the space won't be cleared up. 

If you continue having this issue, please reach out to support@gigwell.com
