The daily update at 2011-04-28 16:23:16 GMT managed to shrink my score from over 50 000 down to 10 000. I just started crunching again after a few months of pause, could this be related? Waiting for the next daily update, maybe it was an anomaly and I'll get my pointies back with the next update.

Thanks for moving the post to the correct forum. That pretty much pointed me to the solution, I hope. It seems my BAM! CPID is different than the one listed in all the projects. Hopefully a simple CPID renewal will fix this.
