urgent issues

Hi,
I really like your plugin and want to get the paid version for my store.
But I face few issues wih free version.
Please help me resolve these so that I can buy and proceed with my work.

My store base currency is USD.

I have enabled the below booster free plugins.

1. Prices and currencies by country
Settings – Detect country by IP and then by user selection
Enabled Price Filter Widget Support
2. Multicurrency product base price
Settings – Have set up the conversion rate for USD to INR and USD to SGD
3. Currency exchange rates
Settings – Have set up the conversion rate for USD to INR

I have two products .

Product 1 :: base currency – USD :: price – 1 USD
Product 2 :: base currency – INR :: price – 1000 INR

Issues faced :

Issue 1 : Price filter and Multi currency product base price
Am from US and on site load, my product prices are converted perfectly.
i.e. Product 1 : 14.9 USD and Product 2 : 1 USD
but price filter shows the range 1 USD to 1000 USD

It has failed to consider the different base currency.

Issue 2 : Mini cart
When country is changed with the widget,my prodcut prices are converted perfectly.
But if there are items in cart alredy , I see that mini cart is not updated.
Only after moving to cart page/checkout page , mini cart gets updated.

Issue 3 : Override Country with Customer’s Checkout Billing Country
When this option is enabled in ‘Prices and currencies by country’ , my store throws internal server error
and site doesn’t load at all.
