I have been using the Slate Digital Virtual Buss Compressor RACK (VBCR) in my master channel in a recent project, which has been working correctly until approx. 2 days ago.  Now when I load the project it crashes as soon as the RACK loads and I cannot proceed further.
 
I have been able to load the project in Safe Mode without the RACK, but why would it stop working all of a sudden?  I have NOT made any changes to my system that I am aware of, no Windows Updates etc.  I have uninstalled and reinstalled the VBCs a couple of times, but the problem persists.
 
Has anyone else experienced instability or crashing with the Slate Digital Virtual Buss Compressor Rack?  I have sent the error report to Cakewalk, but I haven't yet contacted Slate.
 
I have found other threads in the forum that seem to indicate people have been having trouble with Slate plugins, but not the VBC as far as I can tell.
 
I know I can use the plugins in their single forms and they do still work correctly, but now I am concerned that they will stop working for no apparent reason.
 
 
 

You have downloaded the latest version?
Please reset your VST's

Sonar had marked the plugin as incompatible - do I need to reset to make Sonar see the plugin again?  Without resetting, I have tried rescanning a couple of times, but the plugin is still hidden.
 
I am afraid to reset a I don't want to loose my custom plugin layout, I have tried saving it before, but haven't had any luck when reloading it.

Ok, I have managed to get Sonar to rescan and find the VBC Rack, however it still gives me the message that the plugin is not compatible and that I should disable it.

You will need to try a reset if you haven't already. I'm not sure how to backup your settings if indeed this is possible (check the plugin manual/support). Are you sure you are on the latest version of the plugin?

I did check for the most recent version, however it is not available from what I can see on the Slate Digital page.
I seem to recall that they sent me an expiring download link to download it the first time, I will have to ask them if there is a newer version.
 
I have saved my plugin layout to a file in the past and thinking I was safe, reset my VSTs.  Upon reloading the layout I found that it didn't work, my custom layout was gone.  In the end, if I have to recreate the layout I can do that.
 
 

Ok, I've reset and rescanned.  Sonar now finds the VBC Rack plugin and tells me that it is incompatible.

Yup time to contact them for a new plugin then...
At least you know what the issue actually is.
 
Cheers..

I wonder why the plugin was working perfectly fine (at least a month or two) and now it is no longer compatible.
 
I will contact Slate Digital.

Ok, so I did manage to find the user area on Slate and I also realized that I had installed a beta version of the VBC plugins.  I have since installed the last stable version.
 
Now the Sonar VST scan is saying that the Red compressor is incompatible!  This is a nightmare!  How annoying!
