Yup, the Guitar Rig 5 update has annoyed the crap out of me.
Sonar now reports 'unable to find [guitar rig] plugin' in every &*%!$# project that uses it, which is pretty much every single one of my projects. The GR DLL is named exactly the same and it's in the same damn place, but Sonar refuses to recognise it.
Sonar uses some kind of UUID for the plugin, which has obviously changed. I don't know whether it's Sonar or GR generating this, if it comes from the registry or whatever.
I just wish the 'can't find plugin' dialog would give you the option to *search* for the DLL (why doesn't it do this?) Pretty much every project has at least one instance of a tweaked GR patch and now I have no way of recreating all that work. Some might be saved off as GR patches, but given that GR has well over 500 I doubt if I can remember exactly which patch was in each and every instance of GR.
This is incredibly annoying. It's happened before when upgrading Rapture. I might yet encounter it when opening projects with Reaktor player, which also got updated.
Cakewalk, can you do something about this?
