a) Completely un-install SONAR 5 from your computer. This is normally done from Start | Programs | Cakewalk. This will not remove any of your files or audio data.


b) Make sure nothing else is running while reinstalling SONAR in step
'e'. In Win 98/ME/XP, choose Start | Run and type MSCONFIG. Click OK,
then click on the Startup tab at the upper right of the window that opens. Uncheck all items listed, click OK, then restart your computer. You can always recheck those items again at a later time.



c) Click the Windows Start button and select Run. At the prompt type
REGEDIT and click OK.

Backup your Registry before making edits - you do this by clicking File | Export | Export a backup to my documents.

Now delete the following Registry keys

HKEY_CURRENT_USER\Software\Cakewalk Music Software\SONAR 5 PRODUCER

HKEY_LOCAL_MACHINE\Software\Cakewalk Music Software\SONAR 5 PRODUCER



Please note that this will remove any effects presets and key bindings
you may have made in Cakewalk. You can back up those registry keys
separately if you like.


d) Delete the files AUD.INI and TTSSEQ.INI from the SONAR program folder.


e) Restart your computer, then reinstall SONAR

This should eliminate any software irregularities that are causing
your problem
