If you have done that, please make sure that:

1) you don't have an older version of Remote Buddy on your harddrive 
that's started on startup or linked to from your dock.

2) your installed version is a clean install (=> you may want to 
redownload it manually, delete the old copy, then move the new copy to 
its place)

If the issue persists, with Remote Buddy running (important), please 
provide me with some diagnostic information:

1) An ioreg-dump. Create it by entering

ioreg -w0 -l >~/Desktop/ioregDump.txt

into Terminal.app (found in /Applications/Utilities). That creates an 
ioreg-dump file named ioregDump.txt on your desktop.

2) A System Profile. Create it by starting System Profiler.app (found 
in /Applications/Utilities) and choose "Save as.." from the "File" menu.

Please send these two files to info@iospirit.com.

Best regards, 
Felix Schwarz
