From the News Thread a little while again :

"I've just updated the POEM@HOME Binaries to Version 2.00. This is the first big step for our new GPU project. I'll have to adjust some parameters of the new work units, and will send them out at the end of this week.
I'm confident the errors which occurred during the test phase have been resolved. If you encounter any problems nevertheless, please report it in our message boards." - Thomas Koch
