Lost BTCP shares

Hi, I mined for 7 hours yesterday and my shares balance has been at 0. This isn't the first time this is happened. Over the last several weeks I have been noticing more and more that your website has been going down and when this happens shares just disappear

I was one of your early adopters and have been using this this site to mine for awhile now and this issue with dissapering shares was never an problem. I'm not sure whats going on now.
