try this out bud... go to Start/Run/  type in "regedit" (without the quotes).....

click on:

              Hkey_localmachine/software/microsoft/windowsNT/Drivers32.......   you should have a string named wavemapper.... if you don't, on the left pane where it says drivers32: right click/permissions/advanced .........on all the ones that say Deny instead of Allow, highlight the name and click edit... then under the heading Allow check the full control box ....after checking all those you should have wavemapper as a string name in the right pane along with a bunch of new names as well......go to youtube and give it a shot
