Problems with Pages Tab when e commerce is active

Hello

I am new to WP. I installed e commerce plugin as I am trying to develop my own on-line store… Everything worked perfectly fine until I shut computer down and run it again on the morning… When I go to Pages Tab with e-commerce plugin active , it throws this error:

Error 102 (net::ERR_CONNECTION_REFUSED): The server refused the connection.

I am running WP via WAMP at the moment. All other tabs and e commerce itself work fine until I go to Pages Tab. Once, I disable e commerce, Pages Tab works fine. Any help would be appreciated.

Thanks
