Acustica /Acqua plugin issues in C9

Any Nebula/ Acqua users having problems in C9? They work well (for the most part) in 8.5 but using C9 any & all projects eventually freeze up.

The Acustica dev said to report it to SB as they don’t test on Cubsase & feel it Steinberg’s responsibility to investigate any problems I’m having.

Any ideas or setting to check would be appreciated.

Thanks

They seem to work fine here.
