I am unable to reproduce the errors noted in a couple of the posts above. On my machine, I'm getting proper conversion of spaces to underscores and proper recognition of the full colour information in OOTP. It's been almost a year since I last looked as this program, so I'm wondering if maybe I had fixed a couple things and then forgot to release the updated code. In that spirit, I'm releasing a new version, 0.7.1.487, which is the version that I am running on my machine without any issues. Please download the installer and update your utility. If there are still bugs or other issues, at least then we will know it's not just because I forgot to release the most up-to-date build.
