This indicates that the plug-in isn't activated which makes sense since your registered License Keyfile is erased during the Manual uninstall procedure.
If this is persistent and occurs after the manual uninstall ( + reactivating the plugin ) then it's likely that one or several User Presets are corrupted ( like this thread is describing ).
In order to troubleshoot this, test that the ANA 2 GUI and presets browser display is correct after the manual uninstall + reactivation, and before restoring your User Presets backup and overwrite the default installation.
Not sure to understand what you've done here : did you simply created a new folder to store your License Keyfile downloaded from your S.A user account ?
- ANA 2 needs to be activated from the GUI after any 1st time installation or a manual uninstall procedure. The 1st time you'll launch an instance of ANA 2 in your DA it will prompt you to activate and you have to point the GUI to your License Keyfile location on your computer.
--> Your License Key is then correctly registered and processed and gets written in a specific location on your computer, this is the only valid License Keyfile associated to ANA 2 , and again, this file gets deleted during the manual uninstall procedure. Creating a new folder and putting your License Key in there won't work.
On Windows the ANA2.keyfile is created in the following location :
C:/Users/Your_User_Name/AppData/Roaming/Sonic Academy/ANA 2
Deleting all files in this folder will deactivate ANA 2 and reset the plug-in to full default and as explained before, those files are being deleted during the manual uninstall but you can also delete those files on purpose, it's a quick way to get back to full default settings for the GUI, presets library cache database and activation.
Should you need to run the manual uninstall procedure again, please add the following step to delete the VST 3 plugin on your computer (it's missing in the support article ) :
Delete the VST3 Plugin : C:/Program Files/Common Files/VST3/ANA2 x64.vst3
