Hi, Ed,
Steve's suggestions are valid.
However, you didn't indicate the specific release date of OE8.1C your are using. If you don't have a ModRP folder with this file in it and if your report date is correct within the StandardRP folder, it may be that you require a Hotfix to resolve the problem. The release date for the Hotfix is (100208). If this is the case, please contact your dealer and they will be able to provide you with this.
