Pro – Previous data is not displaying and Mailing report is not working

Hi,

I am using pro version of the plugin
I have sent an email to support two days ago on this issue, No response yet. There is no proper support system to this plugin.
So I thought to post my issue here.
I was using a free version of visitor statistics for a month, Recently I purchased pro version and activated. (I have checked the option keep data after uninstalling)
Now i could not be able to see previous data in terms of total page views, total visitors and total unique visitors,. But, in charts and filters the previous data is showing.
Mailing report is also not not working.
Is there any possibility to give option to download reports?
Looking forward to hearing from you as early as possible.

Thanks
