If it's a registry problem with just the DHP program like Bill was saying. Use Revo Uninstall to fully uninstall the program and then reinstall it. Use the Advanced uninstall option so it'll delete any remaining files and registry entries. It can be found at download.com. If it's a problem with the design of the program and that part of the program keeps running out of memory to cause the freeze ups, you can probably increase the memory values so it at least works longer if not stop from freezing up. I haven't used a tuner yet, I'm just looking at it from a software perspective.
