Your preference is set to "gah" (CLI client) or "Genome@Home" (GUI client), I assume? You must be using the F@H client now (from
http://folding.stanford.edu/ ) because the old genome client doesn't work any more. I'm not familiar with the G@H team numbering system, but if you use a G@H team number (604374405), only G@H WUs that you process will give credit to Team AnandTech (F@H WUs will be credited anonymously). If you use a F@H team number (198), both G@H and F@H WUs will give credit to TA, but it will be under the F@H team.
Unfortunately, there is no simple solution to this; you will get a G@H WU if your preference is set as such and one is available. If not, it will "fall back" to F@H WUs. If you want to stick to the old G@H TeAm, you're just going to have to accept that some F@H WUs are inevitable, and the TeAm won't get any credit from those.
