Running Pipmak Max out my CPU

Hi, Pipmak seems to max out my cpu at 100. If I close Pipmak, usage drops to 0-5% normal range. I am running this on hp Paviolion zv6000 ( notebook, Processor: AMD 64 Processor 3500+ with 1.78 GHz.) with 2 GB ram and Windows XP pro with SP3. Any help would be greatly appreicated. cs
