Problems here.
Installed X2a and it would not load Drumagog 4.11, said it couldn't find a file named "C:\Program Files (x86)\Drumagog40\Favorites.dat".
I found the file in a different location and moved it to where Sonar was looking for it. This time Drumagog was recognized but had defaulted to Demo mode.
I Re-installed Drumagog and re-activated it but it still showed up in Sonar as in Demo mode. I tried another install and activation and got the same results.
Also two IK multimedia plugs, CSR Hall reverb & Sampletank 2, were disabled by Sonar. I re-enabled CSR but the instant it loaded up Sonar crashed.
Gave up and restored the computer image I made before X2a was installed. All plugs then worked perfectly.
Very disappointed.
