hahaha, I'm trying to stay in my chair, I'm laughing so hard. Welcome to PHASE 2 as a cruncher!
You sure got through PHASE 1 a LOT faster than I did (I crunched ONLY SETI@home off and on for years on a lowly P4...for a psaltry 349K!)
I honestly think this happens to everyone who crunches long enough, sooner or later. The only solution is to crunch a high paying project, like Maxwell suggested. Either AndrOINC, AQUA, or (at least for now) Primaboinca.
You picked a good one. Watch your credits literally sky rocket in 24 hours.
One other thing - are you all CPU at the moment, or do you have any GPUs to crunch with as well?
