I've been having this repeatedly recently. Every time I try to send a result back, it creates a new profile. Thankfully the problem seems to have stopped now, so it was most likely a problem on grid's end...
I assume ummm... hope that I have not lost all those points. I was just about ready to make it tot he next level.
Don't worry, you haven't lost your points. They're just divided up into different profiles.
Are you still having trouble?
