Nothing but crashes since I got expanded

id uninstall everything including the regestry values and start completely over from the begining,last thing you want is to uninstall a unstable installation and for all the work it takes do it for nothing.

here is how:

For a clean installation of SONAR X1 please try the following:
 
1) Completely un-install SONAR from your computer. This is normally done from Start | Programs | Cakewalk. This will not remove any of your project files or audio data.
 
2) Next you will want to open the Run Command
 
            a) In Windows XP this can be done by going to Start | Run
 
            b) In Windows Vista and 7 this can be done by holding down the ‘windows’ key and pressing ‘r’
 
3) At the prompt type regedit and click OK.
 
***Backup your Registry before making edits - you do this by clicking the File menu, Export Registry File.
 
4) Now delete the following Registry keys:
 
HKEY_CURRENT_USER\Software\Cakewalk Music Software\SONAR PRODUCER\X1
HKEY_LOCAL_MACHINE\Software\Cakewalk Music Software\SONAR PRODUCER\X1
 
*Please note that this will remove any effects presets and key bindings you may have made in Cakewalk. You can back these up separately if you like, using Options|Key Bindings, Tools|SONAR Plug-in Manager, and Options|Colors.  Hit F1 in these views for detailed instructions on how to do this.
 
5) Open the 'Run' command again.
 
6) Copy and paste the following into the prompt:
 
%appdata%\Cakewalk
 
7) This will open your Cakewalk Application Data folder, right-click on the SONAR folder and choose rename.
 
8) Rename this folder SONAR X1 Backup.
 
9) Open the 'Run' command again and type msconfig Click OK and then click on the Startup tab at the upper right of the window that opens.
 
10) Uncheck all items listed, click OK, then restart your computer. You can always recheck those items again at a later time.
 
11) Then reinstall SONAR. Make sure to have any virus scanners disabled on installation. It is not required or recommended to turn off any windows services.
 

This should eliminate any software irregularities that are causing your problem.

then install Producer 64 bit,then upgrade "C",then the "Expanded" package, then Upgrade "D".
 
serioulsy,just follow these instructions and youll be good to go.
this method completely removes sonar from your computer like it was never even there.
so like i said back up any settings (and you regestry just to be safe)
