BOINC seems to have downloaded more than it can handle...I have one processor on this machine and BOINC has downloaded a fair amount too much (according to the hours it will take to crunch each project)...I also have noticed a HUGE drop in my ranking as of late (Im only RACing about 6 creits per day) relative to about 800 per day!...not sure why this happend. How to fix, or if it will fix itself automatically, and how this situation will be handled...

Did you tweak your settings recently?

For an easy way to get rid of all that work: reset the projects.
