Since this i’ve deleted Waves central and all files and logs linked to it, given it full disk access and even taken all security off just to test and see if it would work and no luck it still displayed that message.
also no prompt comes up when opening Waves Central as it says there will be in that error message
It could also possibly be a temporary network issue. If after trying a restart and a possible reinstall it would probably be worthwhile taking it up with tech support.
This issue will require further investigation and troubleshooting.
Feel free to contact our Tech Support department. They will be more than happy to get you up and running with your plugins.
