IntelMole: Are you using the graphical or screensaver? If you're using the graphical, it'll show how many units you have completed in the main screen that displays the 'proteins' folding. Check there, see how many it says you've done. If it says you've completed some, double check your name, and Team #, being sure to check for any whitespaces before your name. If both of those appear to be fine, go ahead and uninstall the program and install it again.
However, you're earlier thought of being a bit slow is a good possibility, you won't show up on the rolls as being a producer until you have 1 unit completed, and I do believe it has to be within the time frame allocated to you. Also, keep in mind, that the base system they are using for time wise is a p2 450, which has gobs more FPU power than the k6-2 you are using.

I'm back from my cross country move if that's who you where referring to.
