If you find that it is taking a long time (ie more than 15 minutes) to synchronise data, you may need to clear out your local browser databases and re-start your browser. This often resolves these problems.
Please follow these steps:
1. Quit Chrome (ie close it completely)
2. Re-open Chrome
3. Make sure you have only one tab with BetterData open
4. With that tab active, follow these instructions
5. Refresh the page and login
