Removing Marketpress breaks the website

Hi,

I was trying to remove MarketPress plugin, upto deactivation, website was working, but as soon as the plugin is deleted, the website only shows blank page even in wp-admin or wp-login (they both show blank white page too).

Website : http://v3.brothersandsistersinlaw.com.au/

This is very urgent as we are about to launch the updated website tomorrow.

Please help.

Thank you,

– Raman
