Had the same problem. Search this thread, you have to fix something in libblkmaker so that it accepts your XPM address.
OK, I redownloaded and recompiled it since the update yesterday and it seems to be mining (no blocks yet). But I noticed that the stepdown from each chain size is much harsher then in the CPU version. With the CPU version, it's like a 90% reduction (eg. 100 4ch/h -> 10 5ch/h) but with the GPU, it's like a 97% reduction. Any idea why?
Also, I keep getting 'Sieve size must be a multiple of 64' warnings during runtime. The sieve size seems to be set to 100,000 by default. Is there a way to change that? I can't seem to find the help info.
