Due to a bug in ATI GPU2 core version 1.01, the core has a bug in how it stores trr files. This makes the files too large, leading to corruption, leading to no points server side. We released a bug fix core yesterday (version 1.02) and it looks like that fixes the problem.
We are doing an automatic core upgrade today (Saturday) at 9:30am pacific time. If you want to fix this before then, you could manually delete your core. The client will then automatically download a new one (v 1.02).
However, if you see that the WU is still in the queue, you will need to delete the WU, either by using qfix or deleting the work directory (which should only be done in between WU's, not while one is running).
