Yesterday I installed Cubase 7 and managed to copy all my plug-ins across just fine except one of them!
I used Cubase 5 before.
When I opened a project that I had on Cubase 5, It recognized all the other plug-ins fine except from FabFilter Pro-Q!
I have used that EQ in so many tracks and I really need it back.
Now the weird part. I can open FabFilter Pro-Q in Cubase 7 and it works well but for some strange reason Cubase wont recognize it when I open some projects!
Here are some images -
