I created a project the other day using Session Drummer 3. when I open the project now I get a message saying this plug-in is missing.  However despite it being in my VST plug-ins folder it doesn't appear to be showing up in the instrument list.  I've done several re-scans and even reinstalled Sonar a couple of times.  But it still shows up as missing.  Does anybody have any idea why this is happening?
 
Error message :

 
Windows Plug-in path:

 
Instrument list not showing Session Drummer 3:

 
Thanks

Is anyone else managing to open Session Drummer 3?

Is the location in the VST Scanner path.

first try a rescan of your plug in manager,
if that doesn't work you can try a reset (back up any custom plug in menu layouts you may have)
if after the reset session drummer 3 is missing from your vst menu then you know a reinstall is needed.
 
move on to this:

youll need to remove session drummer and its contents from the c\programfiles\vst plugins
then do a custom install of sonar again only just installing session drummer 3.
 
it takes about 10 minutes.

Yes it is :

Thank you for your suggestions. I have another issue I need to sort out first.

Well I did a custom re-install of just SD3 and the dll is there but X3 still isn't recognizing neither are any of my other DAW's. I'm not sure if it's worth the effort tracking down the solution as my brain is frazzled I hate getting thwarted through ..

see my post on the other thread (where you commented as well)

I installed SD3 by doing a custom install of Sonar X2 and finally Session Drummer is showing up :) Thank you very much for your help.

glad I could help
