I purchased Navicore several months ago and it worked great until I installed OS2008. I entered my Navicore license code when prompted by the Map application, but it doesn't seem to accept the license. Everytime I try to access map, it prompts me to enter the license code or purchase wayfider. Has anyone else had this problem? I paid a small fortune for the Navicore kit, and now it is worthless with OS2008 installed. Along those same lines, is it possible to somehow remove the license code after it has been entered? Thanks for the help.
