Hello
I bought 2 plug ins alliance (cubase 13) which are in the blocklist
1 Brainworx bx_digital V3
1 Shadow Hills Mastering Compressor Class A
Cubase has put these plug ins in the blocklist and if I try to reactivate it crashes.
Do you have a solution?
Hi and welcome to the forum,
Since this is an English-language forum, we would appreciate it if you could please add an English translation to your posts to benefit users and search engine results.

Thank you!
That means the plug-in doesn’t pass the internal Cubase plug-in test. So, there is an error in the plug-in, which might crash Cubase. Therefore, it has been blocklisted. Get in touch with the plug-in vendor, please.

Thank you I have sent an email to plug in alliance.
If I get the solution it will be communicated in this forum.

I use both these plugins with no issues, in Cubase 14, and going back to digital V2 and Cubase 9.
The solution may be arcane. Or a simple re-install of the plugins.
I’ve had a couple of issues with PA, purchase/licence related, and they have been quick to respond. Fingers crossed.
Hello
I solved the problem somewhat radically.
I restored a backup of my system from January.
I then updated Windows 11, Cubase 13, etc., reinstalled the Alliance plug-ins, and everything seems to be working now.
I think my system was experiencing instability, but I have no idea what caused it.
Thanks for sharing.
