Email stopped working 4 days into the 15 day trial.

Email stopped working 4 days into the 15 day trial.

Here is the quick story:

I opened a 15 day trial of Zoho CRM with the mail add on.

In Zoho's Mail settings I set up POP to send messages to Zoho Mail from my Gmail Account and selected " Enable for Messages that arrive from "04/02/2015" Onwards"
Zoho ignored the " Enable for Messages that arrive from "04/02/2015" Onwards" and started downloading ALL my mail from the day I opened the Gmail account back in 2009.

I kept archiving and it kept downloading. Archiving, downloading, archiving downloading... for 4 days. (I got to about March 2014)

Today Zoho mail stopped downloading or receiving any new messages. I can send.

Checking mail storage shows I have used zero. (see image) I highly doubt this.

Can someone offer assistance? 

cheers
