Point to different data repository issue

Hi, I tried to point the data repository to different server, so i stopped the web service and base service, start the installation file, and point to the new database, it did create the new database on the new server, but the service didn't start after, also, i saw the config files under E:\Documents and Settings\All Users\Application Data\Red Gate\SQL Monitor 2 didn't get updated with the new server info. so does this need to uninstall then install, readd the servers and reconfig to make it works?

we are on 2.1

thanks
