The name of the download file from Atomica is atomicainstall and it may still be on your hard drive somewhere.  I suggest you use Start, Find Files or Folders and see if it is there somewhere.  If you find it, then uninstall the Atomica you have and reinstall by running the program atomicainstall.  If you need me to I can email you the program atomicainstall.  It is 981KB, but I'm not sure your hotmail will take that much.  I have other means to get it to you if necessary.
